The influence of farmland management regimes on wetland bird populations (previous work BD0216)(old BD0224) - BD1309

Description
The widespread degradation of wetlands due to agricultural intensification is considered to have led to a reduction in numbers, and a contraction of the distribution of many species of waterfowl and waders. The principal objective of this project is to quantify the factors which influence the size and diversity of wetland bird populations on agricultural land within ESAs and other designated areas. This project seeks to continue a programme of monitoring at a large-scale, across ESAs, to yield insights into the factors that influence wetland bird distribution and the process of re-colonisation as ESAs mature. This project seeks to complement this large-scale approach with an intensive study on two sites recently acquired as reserves by the RSPB, and on adjacent controls. Comparison of the results of these studies will allow assessment of the relative speed and success with which local wetland bird populations can be restored following implementation of a) a range of Tier prescriptions on land under agri-environment schemes, and b) management aimed primarily at ornithological conservation on reserves. This will facilitate assessment of the probability of successful conservation, rehabilitation or creation of wetland bird populations being achieved by a range of management strategies that have been, or could be implemented under agri-environment schemes. This will be of considerable relevance to the development and implementation of wetland conservation policies by MAFF.
Objective
1. To identify the factors which influence the size and diversity of wetland bird populations on agricultural land within ESAs and other designated areas.

2. To establish the interdependence between water management actions, agricultural management and the ornithological status of wet grassland.

3. To quantify the response of selected invertebrate and bird species to various changes in land-management practices and hydrological regime.

4. To define the relative likelihood of successful conservation, rehabilitation or creation of wetland bird populations being achieved under a range of agricultural and hydrological regimes.
