ASSESSMENT OF IMPACTS OF DEVELOPMENTAL ACTIVITIES ON VEGETATION

AND WILDLIFE

POONAM A. MAHAJANROLL NO. 122021017

( M.Tech-I )

2

Biodiversity

• Ecosystems in a given area. • Great importance at global and local levels.• Store houses of genetic material.• Quantities of foods, drugs, and other useful

products.• The causes of loss and their solutions are local

in scale.

3

SPECIES POPULATION

• Depends on the presence of a suitable environment and availability of resources.

• Abiotic and biotic factors.• Species capable of responding to slow

progressive environmental changes.• Adaptations are required.• Habitat loss.

4

SYSTEMATIC APPROACH FOR EVALUATING BIOLOGICAL IMPACTS

Identification of biological impacts of proposed project

Preparation of description existing biological condition

Procurement of relevant laws and regulations

Impact prediction

Identification & incorporation of mitigation measures

Assessment of impact significance

5

Developmental Activities

• Proper planning at the project level • Role in the overall reduction of biodiversity• Direct impacts on biological systems:1. Infrastructure2. changes in the physical environment 3. industrial pollution 4. impacts on flora and fauna

6

Impacts of vegetation and wildlife

• Intense in rural areas ;• For proposed projects covering large geographic

areas • Studies often focus on threatened or endangered

species

7

• Environmental analyst should assess the possible project or action effects on vegetative ecosystems and wildlife species that are protected by law.

• Systematic approach for this involve mostly:1. Assigning the existing biological resumes2. Impacts analysis of project activities3. Mitigation

8

DESCRIBING EXISTING RESOURCES

• Studies with co-ordination with central, state, and local agencies for information of species

• Goals and objectives reviewed particularly• Photographs and vegetation (habitat) mapping• a supporting technical report to the Draft EIS.• Preliminary work then do any field surveys• Complete the descriptions, habitat features

9

• Environmental analyst should become knowledgeable about the communities.

• Large management plan - more details will be involved in the description of existing resources.

• Analysis can be conducted using computer models.

• A major tool in national forest management is the Management Indicator Species (MIS).

10

IMPACT ANALYSIS

• Depend on thei. specific characteristics of the proposed project

alternatives and ii. the expected degree of effects• Loss of Valuable Vegetative Community Types• If the vegetation is common and unremarkable• high-quality functional value, namely wildlife

habitat, erosion control, recreational use

11

• Direct Loss of Wildlife and Habitat• Removal of natural vegetation - loss of habitat • Larger species may immigrate to adjacent areas• Community will already be at its carrying

capacity for the particular species• Imbalance to the species population

12

RECREATIONAL USE

• Direct or indirect impacts to vegetation produce secondary effects on recreational resource values

• Urban environments can support recreational activities

• Both active and passive recreational activities comparatively assessed and quantified.

13

FACTORS TO BE CONSIDERED IN MAKING ASSESSMENT DECISIONS

Magnitude

Prevalence

Duration and frequency

Risk

Importance

Mitigations

14

CONCLUSION

• Changes in vegetation cover produce alterations.

• altering the global climate.• the carbon and water cycles.• Rapid growths in population, urbanization,

industrialization, damages to the environment.• “Urban Heat Island Effect” occur.
