What Is Biological Monitoring?
Regular checking of the changes in a habitat by examining its species after regular intervals.
LAWRENCE GARDEN
• John Lawrence built the garden as a
botanical garden.
• Originally covered 176 acres.
• Current area: 121 acres (0.49 km2).
STEPS FOR MONITORING SHOULD BE PLANNED
BEFORE STARTING MONITORING
BIOLOGICAL MONITORING OF LAWRENCE GARDEN
FLORA OBSERVED: 150 varieties of trees, 140 types of shrubs, 50 types of creepers, 30 kinds of palms, almost 100
succulent plants

Net casting spider
Common Lizards
Dwarf Tree Frog
Insects• Butterfly• Wasps• Ants• Hoverfly• Blowfly• Rose Aphid• Lady Bugs
SOIL SAMPLING• Random soil sampling
• Surface soil sampling
• 2m depth
• Use hand augers and shovels
• Wash using 75% ethanol and 10% alcohol
SOIL SAMPLE PROCESSING
• Sample should be air dried firstly.
• Should be sieved through a 2mm mesh.
• Should be stored in a plastic bag and used
immediately
• Or it can be stored at 4oC for future
analysis.
WATER SAMPLING FOR RECREATIONAL SITES
• Water samples must range from 200ml to 1000ml
• Use plastic bottles and glass jars.• Water is stored at cool
temperatures • Bacteria can be filtered by using
0.45microns filter.
AIR SAMPLING
• Impingement
• Impaction
• Centrifugation
• Filtration
Commonly used devices for Microbial Analysis of Air
• All Glass Impinger (AGI).
• Anderson Six Stage Impaction
Sampler.
METHODS FOR COUNTING MICROORGANISMS PRESENT IN A SAMPLE
HETEROTROPHIC
PLATE COUNT
Microscope Direct Count
• All organisms are
directly counted by
using a microscope
• Time consuming
STANDARDS FOR MICROBIAL POPULATION IN RECREATIONAL AIR, WATER AND SOIL
IN WATER:
• 7 total coliforms per 100ml of
water
• Non coliformic 200 organisms
per 100mlof water
In Air:
Fungal spores <500CFU/m3
Bacteria 5000CFU/m3
IN SOIL:
Amount of fungal spores and
bacteria should be between
100-500CFU/m3
Steps to be Taken
All environmental organizations
should pay attention towards the
well being of this remarkable
garden to support beautiful and
unique species of Pakistan.
