On diversity effects of alternative agricultural policy reforms in Finland: An agricultural sector modelling approach [PDF]

, 2003
The aim of this study is to predict diversity effects of agricultural policy reforms in which direct aid payments are disconnected from production, and compare the outcomes with effects of such a policy in which CAP support is coupled.

Breeding bird response to adaptive multi‐paddock and continuous grazing practices in Southeastern United States

Ecosphere
Grassland bird populations are declining steeply, reflecting the degradation and loss of native grassland habitats. To assess how grazing management affects declining grassland bird populations, we compared breeding avifaunal communities in adaptive ...

Database of bird species composition in natural habitats and forest plantations

Data in Brief, 2019
In southeastern South America, the afforestation over grasslands imposes a severe threat to the grassy landscapes and associated biodiversity. To analyze the effect of forest plantations on grassland birds, we present a new database that considers the ...

Organic farming: technology transfer (Environmental impact and soil fertility) (OF0405) [PDF]

, 2003
This project covered two separate activities, but both were examples of technology transfer, relating to organic farming: 1. Developing a science-based report, which covered an assessment of the environmental impacts of organic farming. Defra’s Action

Breeding songbird use of native warm‐season and non‐native cool‐season grass forage fields

Wildlife Society Bulletin, 2017
Converting fields of non‐native cool‐season grasses to native warm‐season grasses has been proposed as a strategy to enhance avian habitat and diversify forage production for livestock, but may yield poor‐quality food and cover for birds.

Breeding success of Black-tailed Godwits Limosa limosa under 'mosaic management' : an experimental agrienvironment scheme in The Netherlands [PDF]

, 2012
Black-tailed Godwits (Limosa limosa) have been declining for decades in The Netherlands and so far this has not been slowed by conservation measures. A new form of agri-environment scheme was tried out in 2003-2005 at 6 sites where a ‘grassland mosaic ...

Monitoring Grassland Bird Communities with Acoustic Indices

Birds
Several researchers have tried to find relationships between acoustic indices and vocal animal communities to use acoustic indices as a passive monitoring method, as human-derived surveys are expensive, time-consuming, and suffer from observer bias.
