Rangeland Monitoring is the orderly

both short-term and long-term

management decisions.

Rangeland Monitoring is the orderly

collection, analysis, and

interpretation of resource

information and data used to make

both short-term and long-term

management decisions.

Here is the basic definition of range monitoring. Notice that analysis and interpretation are

an important part of the definiton, and that the end result is decision making. It is not

enough to take pictures or run transects without spending time thinking about what the data

tells you, and then adjusting your management appropriately.

We’ll discuss the question of what monitoring is in further detail a little later in the

presentation.

Why MonitorWhy Monitor

• Determine if management

objectives are realistic and

achievable.

• Determine if grazing

management strategy meets

goals for resource and

livestock conditions.

• Determine if management

objectives are realistic and

achievable.

• Determine if grazing

management strategy meets

goals for resource and

livestock conditions.

Before spending a lot of time on the details of monitoring, it’s important to consider why we

monitor. What are the benefits?

Why MonitorWhy Monitor

• Provide a record of resource and

• Assist producers in managing

livestock

• To evaluate when management

strategy changes are needed to

better meet identified objectives.

Many Permittees and Agency Managers have made the comment that monitoring provides

them with a way to document their decision-making procedure. Some refer to this as being

able to document their stewardship. So, if someone comes along and questions their

management decisions, they can pull out this record and say, “here’s what we decided the

area should look like, here’s the management actions we have taken and here is the

information and data that suggested we do what we did.”

Back to the discussion of What is Monitoring.

Monitoring is a commitment, because it is an ongoing process that involves data collection, analysis,

interpretation, and decision making.

The central goal of monitoring is to determine whether progress is being made toward achieving

objectives. Of course, we all want to make good management decisions and these are the ones that

are consistent with the objectives set for a given area. This assumes that objectives have been

established.

ObjectivesObjectives

• Objectives describe what we want the

ground to look like.

• Good objectives

– plant community or natural resource based

– include input from agencies, operators and

society’s needs

• Objectives are directly tied to the system’s

response(s) to

– our management inputs

–Mother Nature’s inputs

• Objectives describe what we want the

ground to look like.

• Good objectives

– plant community or natural resource based

– include input from agencies, operators and

society’s needs

• Objectives are directly tied to the system’s

response(s) to

– our management inputs

–Mother Nature’s inputs

For Public lands, objectives and goals are driven by the Management or Forest Plan,

Allotment Management Plan and the Annual Operating Instructions. For Private lands these

objectives will be driven by the landowners goals and objectives. Overall goals and

objectives can be done by a team made up of the landowner, NRCS, Extension, Agency, or

other interested entity.

Long-Term Monitoring:

System responses –

How has the plant community changed?

Is there more or less bare ground?

What species are increasing in the community?

What species are decreasing?

How is the soil changing?

Is erosion occurring?

Are we making progress toward our objective?

Measuring management and environmental factors.

-What were the frequency, intensity, and duration of grazing?

-Was this a wet or dry year?

-What was the impact of wildlife?

How might this year’s events affect our progress toward our objectives?

How might the system respond to these events?

• Special Areas (critical areas)

“Key areas are sampling units that characterize general range conditions over large areas

such as pastures or grazing allotments.” (Schalau 2001)

“Critical Areas are those containing special or unique values such as endangered species,

riparian habitats and fragile watersheds.”

(Schalau 2001)

Key areas are chosen based on how well they represent the larger area/pasture/allotment.

Key areas need to be consistent in vegetation type, slope, soils or ecological site description

area, etc.

•Not practical to monitor every acre

•It is essential to select monitoring sites

that represent larger management areas.

•One or more key areas should be

• Avoid areas such as fences, salt locations,

stock trails, ridges, or unused areas.

If each unit or pasture is predominately one veg type then one site will work. If the unit is a

mix of upland and riparian then one in each will work. Or the site may be made up of two

different upland types so one in each may be warrented.

A single photo from a permanently marked site of a impacted area can be very

effective in demonstrating resource recovery or the need to modify current

management.

Finding the location of an old photograph and retaking it can provide good

information on past use and trend of the site.

Bear Creek Allotment, Wind River Ranger District, Shoshone National Forest

Allotment changed permittees. Some mistakes that were made, like salting in this riparian

meadow, are now being tracked to see how the new management is effecting the recovery

of the salting area or this head cut area. The pictures tell the story.

This allotment uses a deferred rotation system and has active monitoring program.

This method estimates general forage utilization.

It is especially helpful when grazing or browsing use must be estimated for large areas.

For this method, an ocular estimate of forage utilization is based on the general appearance of the rangeland.

Utilization levels are determined by comparing observations with the written utilization class descriptions.

Utilization estimates are evaluated against the standards, goals, or objectives for the area.

WhyWhyWhyWhy::::

� Describe annual grazing use, interpret annual grazing effects, and plan the grazing pattern for the following year.

Developed to describe annual grazing use, interpret annual grazing

effects, and to aid in planning the grazing pattern for the following year.

Understanding plant physiology and plant response to grazing is essential in the

development of unit management plans; with this there is a need for a monitoring tool that

adequately estimates rangeland use due to grazing

Must not only access how much of the plant was grazed but also when the plant was

grazed and how many times it was defoliated during the growing season

GRI is an effective tool to access grazing systems or complications associated with

situations such as early season big game use followed by livestock use

Consequently, GRI is based on general determinations of annual grazing use, and is not

intended to be the only method for resolving major conflicts.

GRI considers three key concepts related to plant health: frequency,

intensity, and opportunity

32

GRAZING RESPONSE INDEX

GRAZING RESPONSE INDEX

• Frequency - the number of times plants are defoliated during grazing period

• Intensity – of defoliation is the amount of leaf material removed during grazing period (Utilization)

• Opportunity – is the amount of time plants have to grow prior to grazing or regrow after grazing.

• Frequency - the number of times plants are defoliated during grazing period

• Intensity – of defoliation is the amount of leaf material removed during grazing period (Utilization)

• Opportunity – is the amount of time plants have to grow prior to grazing or regrow after grazing.

Dependent on the length of time plants are exposed to grazing animals;Approx. 7-10 days required for a plant to re-grow enough to be grazed again during late spring or early summer when plants experiencing rapid growth

Utilization; the primary concern is the amount of photosynthetically active leaf material remaining for the plant to recover from grazing

Opportunity is the one factor most highly related to long term health and vigor of the vegetation

Vegetation provides streambank protection, traps sediments, contributes to rebuilding degraded stream channels, and ensures residual forage and habitat.

Retaining an adequate amount of standing herbaceous vegetation (stubble) along the streambanks and within the primary floodplain slows overland water flow velocity from winter and spring runoff, traps and retains sediments necessary to build and maintain streambanks.
