Good ag neighbors: Rare remnant plant species are better conserved in larger forest patches next to ag lands than urban

Because of publisher copyright restrictions I can't share the research abstract, however I can summarize an interesting study in 2006 that found that agricultural lands are better neighbors than urban land use that adjoin remnant woodlots. The study that was done in Spain found that plant species recorded were compared to levels of human disturbance and frequency. Results were determined that disturbance-type plant species decreased with increasing distance to forest edge. Rare forest species were richer in large patches adjacent ag-based lands as compared to small woodland patches in peri-urban areas.
