A.P.E.S. Dashboard Tutorial 1
GETTING STARTED
STEP 1: SELECTING REGION OF INTEREST
When loading the A.P.E.S. Dashboard you will be presented with introductory text which asks you to choose
the region you are interested in exploring (figure 1). Significantly different socio-economic conditions within
Asia and Africa prohibit the direct comparison of normalised scores across the regions. Therefore, you will
need to analyse Important Ape Sites (IASs) within one region (i.e. Africa or Asia) at a time. If you would like
to change the region of analysis you will need to re-load (or refresh) the A.P.E.S. Dashboard. Once a region is
selected, the dashboard will load results for all sites in that region (figure 2).
Figure 1. Introductory page with the region selector buttons highlighted.
Figure 2. The A.P.E.S. Dashboard displaying all Important Ape Sites in Africa.
A.P.E.S. Dashboard Tutorial 2
STEP 2: SELECTING TAXA/COUNTRIES OF INTEREST
Once a region has been selected, the A.P.E.S. Dashboard will display all sites which fall within that region.
The next step is to select the taxon/a of interest (species or subspecies), the country/ies of interest, or a
combination of both. This can be done using the “Taxa” and “Countries” filters in the upper left hand area of
the dashboard (figure 3).
Figure 3. The location of the Taxa and Countries filters.
The “Taxa” filter is based on a drop-down menu. Taxa are first classified into Great Apes or Other Apes
(Gibbons), and then into families/genera (figure 4). The “Countries” filter is based on a drop-down menu
which lists all countries (within the selected region) where apes occur (figure 5).
If you are interested in a particular taxon, in a particular country you can combine filter selections. For
example, to analyse sites of the Western Chimpanzee in Guinea select Western Chimpanzees in the “Taxa”
filter and Guinea in the “Countries” filter. Please note, if you select a taxon in a country where it does not
occur the Dashboard will display an empty graph/map/table.
A.P.E.S. Dashboard Tutorial 3
Figure 4. Examples of the Taxa filter drop-down menus for (a) Great Apes in Africa and (b) Other Apes in Asia.
Figure 5. Countries drop-down menus for (a) Africa and (b) Asia.
Once the filters are set, all sites that fulfil the selection criteria will be shown in the graph/map/table. For
example, if “Great Apes” and “Cameroon” were selected in the filters, all sites which fall (a) in the extent of
occurrence of any great ape species and (b) within Cameroon, would be displayed in the graph, map and
table.
A.P.E.S. Dashboard Tutorial 4
STEP 3: SLIDER BARS
There are three slider bars that allow you to refine the selection of sites shown in the graph/map/table. These
are based on three attributes: (1) Response score for the site, (2) Biodiversity score for the site and (3) Area of
the site (in km2) (figure 6). The minimum and maximum values shown on the slider bars correspond to the
minimum/maximum possible values for each slider variable within the selected region (figure 6).
Figure 6. The Response, Biodiversity and Important Ape Site Area slider bars (demonstrated for African sites).
Sliders on the slider bars can be dragged to a desired value. Alternatively, the desired value can be typed in
the appropriate text box. Altering the slide values will exclude sites from the graph/map/table which do not
fall within the selected value ranges. For example, if you are only interested in sites which (a) are at least 100
km2 in extent, (b) have a low Response scores (less than 0.5), and (c) have a high Biodiversity scores (greater
than 0.4), you can either drag the sliders to the desired values (0.5, 0.4 and 100 for Response, Biodiversity and
Area, respectively) or type the values into the slider labels (figure 7). All Important Ape Sites with low
Response scores (less than 0.5), high Biodiversity scores (greater than 0.4), and which are greater than 100
km2 in extent will be displayed. Please note, the selected region, taxon/a and country/ies will also influence
the sites displayed.
A.P.E.S. Dashboard Tutorial 5
Figure 7. Example using the Response, Biodiversity and Area slider bars. Results show, for a selected region,
taxon/a and country/ies, all Important Ape Sites with low response scores (less than 0.5), high biodiversity
scores (greater than 0.4) and area of at least 100 km2
STEP 4: FILTERING BY SITE CATEGORY
A final element that will help you target your analysis, and selected sites, are the site category buttons (figure
8). All sites included in the A.P.E.S. Dashboard can be classified into three categories: Landscapes, Action
Plan Sites, and Protected Areas. These categories reflect both the scale and definition of the sites. Landscapes
are the largest sites defined by CARPE and Arcus Foundation consultants. Action plan sites are intermediate
in scale and were defined within the great ape species action plans. Protected areas sites are those sites with a
national protection status where apes are thought to occur. Full details of the Important Apes Sites, and their
definition, is given in the methodology document.
By default, all three categories of site are selected. When selected the buttons appear in blue (figure 8).
Selections based on all combinations of the site categories are possible (figure 9).

plan.
A.P.E.S. Dashboard Tutorial 7
STEP 5: OUTPUTS
The A.P.E.S. Dashboard features three different outputs to support Important Ape Site analysis. These are a
graph, map and table. Each of these elements can be visualised within the Dashboard (figure 10).
Figure 10. Visualization of A.P.E.S. Dashboard outputs.
GRAPH
The most informative of all outputs, the graph enables the visualization of four dimensions, that is, the
Pressure score, Habitat score, Response/Biodiversity score, and IAS area (figure 11). It is the relative position,
colour and size of the sites which needs the most consideration.
Figure 11. The A.P.E.S. Dashboard Graphical output.
A.P.E.S. Dashboard Tutorial 8
Key interpretation elements on the graph are:
a) Pressure: The Y-axis expresses the overall site pressure score. A high pressure score indicates that
one (or more) taxon at that site encounters high pressure relative to the values found in its extent of
occurence.
b) Habitat: The X-axis expresses the overall site habitat score. A high habitat score indicates that one
(or more) taxon at that site encounters high amounts of tree cover (canopy cover) relative to (a) the
taxons preferred habitat structure and (b) vegetation cover found in its extent of occurrence.
c) Response: Darker colours (brown), on the response scale, indicate higher values. A darker coloured
site has a higher protection extent and/or protection category than a lighter coloured site.
d) Biodiversity: Darker colours (dark-blue), on the biodiversity scale, indicate higher values. A darker
coloured site has the potential to contain a relatively high number of vertebrate species (when
compared within a region), a high proportion of threatened vertebrate species and/or relatively high
carbon stock (when compared within a region).
The response and biodiversity scores are visualised one at a time on the graph. You therefore need to select
the variable of interest by clicking on the “show” button next to the slider bar (figure 12).
Figure 12. Showing sites response or biodiversity scores on the graph.
e) Combining pressure and habitat: A significant advantage of a graphical output is the ability to
compare the relative value of sites on the pressure and habitat score axes simultaneously. Proactive
and reactive conservation priorities can be easily considered via the sub-division of the graph into
four quadrants (figure 11). If you are considering a reactive approach sites with higher vulnerability in
the upper quadrants will be of most interest. These quadrants contain sites with high pressure scores,
indicative of sites under immediate threat of destruction. Conversely, if you are considering a
proactive approach sites in the lower quadrants will prove more interesting. Sites falling within these
A.P.E.S. Dashboard Tutorial 9
quadrants have the potential to be preserved against future threats, either with good habitat
condition or with the potential for rehabilitation.
MAP
The spatial context of Important Ape Sites is best analysed via the map display. The background map enables
you to explore the position of the site relative to major urban areas, roads and rivers (figure 13). Datasets
included in the scoring of sites such as population, deforestation and forest cover are also included in the
map display (figure 13). It should be noted that the map display contains aggregated Extent of Occurrence
maps for the Gibbon species. Aggregation to the Genus was required to provide a clear cartographic display.
This generalisation to the Genus level is only for display purposes. As per the other ape species Gibbons are
analysed to the most detailed taxonomic level available (see methodology document for details).
Figure 13. Dashboard outputs allow site locations to be mapped against (a) a background layer showing roads,
cities and rivers, and (b) datasets included in the scoring of sites.
A.P.E.S. Dashboard Tutorial 10
TABLES
The graph does not display the actual values for the pressure and habitat scoring components. Detailed site
comparisons are therefore reliant upon the values included in the summary table. Two tables are available for
download (figure 14). The simplified tables (as displayed on the website) include a summary of site scores
only. The detailed results tables (available for download only) include all scoring component values plus
additional information in the form of actual parameter values, for example, average percent deforestation.

A.P.E.S. Dashboard Tutorial 11
ANSWERING QUESTIONS WITH A.P.E.S. DASHBOARD
There are two possible scenarios when starting your analysis: (a) you have particular species or countries of
interest, or (b) you have no specification but wish to explore a range of ape conservation options. We will
work through an example in order to show the full functionality of the A.P.E.S. Dashboard and the questions
it can help answer including:
Which are the most/least threatened important ape sites and where are they?
What is the protection status of important ape sites?
Which important ape sites are most significant for other species and ecosystem services?
CASE STUDY: CONSERVING CHIMPANZEES IN THE CONGO BASIN.
In this example a hypothetical user is interested in Chimpanzee conservation (Eastern, Western, Central and
Nigeria-Cameroon chimpanzees) within the Congo Basin. The first steps in setting up this analysis are to (1)
select Africa as the region of interest on the landing page, (2) select all chimpanzee taxa in the Taxa filter
(figure 15a) and (3) select, from the Countries filter, all countries that are part of the Congo Basin (Cameroon,
Central African Republic, Gabon, Congo, Democratic Republic of Congo, Rwanda, Burundi, and Tanzania)
(figure 15b).
Figure 15 (a): Selecting the Chimpanzee taxa
Figure 15 (b): selecting countries of the Congo basin
The A.P.E.S. Dashboard identifies 159 Important Ape Sites where actions towards the conservation of
chimpanzees in the Congo Basin could take place (figures 16 to 18). At this point three basic questions can be
answered:
Which are the most/least threatened important ape sites and where are they?
By dividing the graph into quadrants you can easily identify the group of sites under highest relative
pressure, either with low or high relative habitat condition (upper-left and upper-right quadrants,
respectively) (figure 19). The hover function allows you to identify the sites on the graph, and with
this site ID it is possible to locate sites on the map (figure 17 and 18).
What is the protection status of important ape sites?
The colour gradient in the response slider bar allows you to easily identify in the graph those sites
with higher/lower response scores. Given that the response score is a combination of protection
category and extent, using the colour scale and hover function you are able to identify the protection
A.P.E.S. Dashboard Tutorial 12
status of different sites (figure 16). A high Response score, shown with darker colours, is indicative of a
higher protection extent and/or protection category than a lighter coloured site.
Which important ape sites are most important for other species and ecosystem services?
The colour gradient in the biodiversity slider bar allows you to easily identify in the graph those sites
with higher/lower biodiversity scores. The biodiversity score is a combination of non-ape species
richness and carbon stocks within the site (figure 17). Therefore, sites with a high value (darker
colours) have the potential to contain a relatively high number of vertebrate species, a high
proportion of threatened vertebrate species and/or relatively high carbon stock.

A.P.E.S. Dashboard Tutorial 15
The previous analysis has identified a selection of Important Ape Sites (IASs). However, in order to target
your conservation actions you need to start thinking about your conservation priorities and options. In this
example, we are going to use the scenario that the user is only interested in sites that were defined by the
Apes conservation community as an ape action plan site. To meet this criterion and refine the list of sites you
need to un-select Protected Areas and Landscapes (figure 20). This reduces results to 51 possible IASs.
Figure 20. Case study results filtered to include only Action Plan Sites
Continuing with the example, the user’s conservation strategy is to increase the protection level of Important
Ape Sites. Simultaneously, they would like to protect the sites with highest biodiversity scores. Given that the
proposed conservation action in this example is to protect sites, to be considered it is specified that sites
should have a maximum area of 10,000 km2. You can narrow down the 51 sites to fulfil these requirements by:
1. Moving the right-hand Response slider to 0.5 (figure 21)
2. Moving the left-hand Biodiversity slider to the mid-point of the slider bar (figure 21)
3. Typing “10,000” in the right-hand box of the IAS Area slider bar (figure 21)
A.P.E.S. Dashboard Tutorial 16
Figure 21. Case study results filtered by Response, Biodiversity and Area criteria
In this example, by using funding restrictions, interests and possible conservation strategies the A.P.E.S.
Dashboard helped identify a subset of 9 sites (out of 347) where conservation actions could support the
conservation of apes in Africa. These sites can be further explored and refined with specific analysis, study
and data collection.
There is no “one” answer when using the A.P.E.S. Dashboard, which sites most need conservation actions will
depend on who is using the tool, what their priorities are, and which conservation actions are to be applied.
This is why interpretation of the results is crucial. These results can be visualised and further analysed using
the graph, map and tables to answer more detailed questions.
DETAILED ANALYSIS OF THE FINAL SUBSET OF SITES
More detailed questions that the A.P.E.S. Dashboard outputs can help to answer are demonstrated below.
1. Which sites should be prioritised?
The selection of sites to receive future conservation action depends on the desired conservation approach
whether it is to prioritise high vulnerability sites or the preservation of good-quality low vulnerability
sites (figure 22).
A.P.E.S. Dashboard Tutorial 17
Figure 22. Proactive and reactive conservation approaches superimposed on the refined case study results.
2. Which sites are under the most/least pressure?
From the graph you can clearly distinguish the highest/lowest pressure scores (figure 23). There are several
sites grouped in the middle of the pressure axis. The pressure scores for these sites are very similar and
additional external information is required in order to differentiate between them.
Figure 23. Identifying sites with the highest and lowest relative pressure scores.
A.P.E.S. Dashboard Tutorial 18
3. Where are the sites under most/least pressure?
The locations of the 9 sites in the final selection are displayed in the map (figures 24). Sites are shaded in
black on the map. The identify function (activated by clicking on sites), when combined with the graph,
enables the identification of sites with the highest/lowest pressure scores.
Figure 24. An example map for a subset of the case study results. Site 48 has been highlighted with the
identify tool.
4. How does the location of sites vary relative to know threats?
The pressure score for each site was calculated using datasets as proxies for threat. Datasets utilised
include, deforestation (%), the human influence index, human population change (%) and human
population count. These datasets have been added as layers that can be displayed in the map. These
layers will enable you to visualize the location of sites relative to these threats (figures 25 and 26). The
base map enables you to explore the position of the site relative to major urban areas, roads and rivers.
In the case study, a visual interpretation of the human population change layers reveals that Important
Ape Site 1036, “Virunga” is located next to an area that has experienced relatively high population growth,
as indicated by the darker coloured census districts (figure 25), when compared to the areas adjacent to
remaining sites (figure 26).

A.P.E.S. Dashboard Tutorial 20
5. Which sites have the highest/lowest habitat condition and what is their location relative to high vegetation
cover areas?
In the same way that questions three and four were answered, by looking at the habitat scores, displaying
the forest cover layer in the map, and using the hover function the highest/lowest habitat score sites can
be identified (figure 27). The location of these sites relative to high forest cover areas can be explored in
the map (figure 28). In this example, all sites have a very similar, relatively high habitat score.
Figure 27. Case study sites with the highest/lowest relative habitat scores.
Figure 28. Comparing sites to the forest cover layer. Note: darker colours indicate a greater proportion of
vegetative cover.
A.P.E.S. Dashboard Tutorial 21
6. Which sites have no/the most protection and where are they?
The colour scale in the response slider bar allows you to easily identify in the graph those sites with the
highest/lowest response scores. A high response score (darker colours - brown) is indicative of a higher
protection extent and/or protection category than a lighter coloured site. Conversely, a lighter colour
(yellow) is indicative of a lower protection extent or protection category. In this example, there are three
sites with little or no protection, as indicated by a response score of zero (figure 29). The remaining five
sites have a score (and colour) which ranges between 0 and 0.5 (that is, the highest values within the
selected range of values).
Figure 29. Comparing the case study sites on the basis of their response scores.
A.P.E.S. Dashboard Tutorial 22
7. Which sites have highest biodiversity score and where are they?
The colour scale in the biodiversity slider bar allows you to easily identify in the graph those sites with the
highest/lowest biodiversity scores. Sites with a high value (darker coloured, dark-blue) have the potential
to contain a relatively high number of vertebrate species, a high proportion of threatened vertebrate
species and/or relatively high carbon stock. In this example the biodiversity scores for all sites are very
similar (figure 30), ranging between 0.46 and 0.62 (where 0.4 is the lowest value within the selected
range). This similarity of values makes comparisons harder, but the hover function helps identify the
relative score values for each of the sites (figure 30).
Figure 30. Comparing the case study sites on the basis of their biodiversity scores
A.P.E.S. Dashboard Tutorial 23
To make detailed site comparisons you will need to combine the graph and tabular outputs of the A.P.E.S
Dashboard. This is essential as the graph does not display the actual values for each of the scoring
components. The following questions exemplify how to combine these two elements.
8. Which taxa are present in the different sites? Are there multiple taxa?
Counting from left to right, the 9th column of the summary table displays which taxa (of those selected for
analysis) are present at the site (figure 31). It should be noted that the site may contain more ape taxa than
those listed. The list considers only whether the taxa of interest (those selected in the filter) occur in a given
site. The analysis taxa present field provides two types of information: (a) if all apes are selected, it enables
the identification of multiple taxa occurring at the same site; and (b) based on the initial taxa selection, it
provides valuable detail to support the refining process. For example, in our case study seven out of nine sites
that result from the analysis are sites where “pte” occurs (Pan troglodytes ellioti, Nigeria-Cameroon
chimpanzee, see Methodology document for a complete list of taxa codes). Given the refining criteria (all
Action Plan Sites in the Congo Basin where chimpanzees occur, protection is low and biodiversity is high)
this dominance of “pte” sites could be interpreted that, of all Action Plan Sites in the Congo Basin where
chimpanzees occur and biodiversity is high, the Nigeria-Cameroon chimpanzee is the taxon with the most
unprotected Action Plan Sites.
Figure 31. Summary results table for the case study sites. The ‘Analysis Taxa Present’ column is highlighted.
A.P.E.S. Dashboard Tutorial 24
9. Are there any differences in the confidence surrounding the scores for the different IASs?
The last column in the summary table displays the uncertainty score for each site (figure 32). The
uncertainty score provides a relative estimate of the confidence surrounding scores derived for a given
Important Ape Site. Varying levels of uncertainty between sites are a consequence of two elements, (a)
the extent of the analysed area, and (b) dataset availability.
It should be noted that the uncertainty value is a score (from 0 to 1). Consequently, it should not be
interpreted as an absolute accuracy value. The utility of uncertainty scores is to compare the relative
values between sites, not the absolute value. In the example case study, when sites are compared, the
“Tubah-Awing” site (number 65) and “Mount Kupe” site (number 56) have almost double the uncertainty
score of remaining sites. This indicates that the scores associated with these sites should be interpreted
with more caution.
Figure 32. Summary results table for the case study sites. The ‘Uncertainty’ column is highlighted.
10. Which threat proxy is driving the pressure score for the site?
The relative pressure on ape populations within a specified Important Ape Site, was calculated via a
set of proxies (human population, deforestation, human influence index, and temporal changes in
habitat suitability). The definition of the overall pressure score is the maximum score derived from
any of the four proxies for a taxon. This taxon specific pressure score is available in the detailed result
table (download only). Counting from left to right, the 8th column (“Main Pressure”) in the detailed
results table (download only) displays the main pressure determining the Pressure score (figure 33)
for a given taxon at a given site. In this case study, HII (human influence index) is the main pressure
for all 8 Important Ape Sites.
A.P.E.S. Dashboard Tutorial 25
Figure 33. A subset of the detailed table results (download only) for the case study sites. The ‘Main Pressure’
column is highlighted.
11. What are the actual parameter values for the different threat proxies measured for each site?
The scoring of Important Ape Sites is primarily based on the mean environmental/pressure conditions
encountered, but these parameters are normalised to produce scores which describe the relative score of
the site for the particular taxon being analysed. Counting from left to right, columns fourteen to twenty-
two in the detailed results table (download only) display the main parameter values used for scores
estimations for each site: Mean Forest Cover (2005) (%), Mean Deforestation (2000 - 2005) (%), Mean
Human Influence Index, Mean Population Count (2000), Mean Population Change (1990 - 2000) (%),
Protection Extent (%), Maximum Species Richness (MSR), Proportion MSR Threatened (%), and Mean
Carbon Stock (tonnes/ha).
12. If it is an Action Plan Site, is it a priority conservation area or survey area?
Action plans for African apes usually include two broad categories of priority areas: priority conservation
areas and priority survey areas. The last column in the detailed results table (download only) displays any
additional available information for the site. Additional information is a function of the site types, for
example, protected areas include their unique global ID (WDPAID) and designation, landscapes outline
the organisation responsible for the delineation/definition of the site and action plan sites identify the
specific species action plan and priority site category.
This example demonstrates some of the questions that can be answered with the A.P.E.S. Dashboard.
However, it is not an exhaustive list. As previously stated, there is no unique answer when using the A.P.E.S.
Dashboard; results will depend on who is using the tool, what their priorities are, and which conservation
actions are to be applied. The dashboard enables users to identify a subset of focal sites that match different
conservation strategies, but results should be further refined through detailed analysis, study and data
collection to guide conservation actions within the final group of sites.
