Landscape Science for Nature and For People

Welcome to the Haddad Lab

We study the application of ecological principles to the conservation of biodiversity - from individual rare animals, to all species living within a community, to species effects on ecosystems and people. We focus on strategies like habitat corridors that are intended to overcome the negative effects of habitat loss and fragmentation, and the effects of land use intensity in diversified agricultural landscapes that increase ecosystem services such as pollination.
