The impact of beach grooming on coastal habitat
by Rob Goldstein in Conservation Maven
A new study from Southern California affirms that the long-standing management practice of beach grooming is contributing to the loss of coastal strand habitat. Coastal strand plant communities grow along the edge of the high tide line and are comprised largely of endemic species adapted to grow in the dynamic, environment of loose, shifting sand......

Protected areas lead to long term transformation of marine ecosystems
by Rob Goldstein in Conservation Maven
Results from a new study in Australia affirm the ability of "no take" marine protected areas to aid the recovery of overfished ecosystems. Researchers found that the reefs within three marine protected areas off eastern Tasmania transformed over time into communities not otherwise seen in the regional seascape, and these changes intensified for at least 16 years....

The value of 'ignorance' in restoration

Minimizing the impact of approaching boats on nesting shorebirds
by Rob Goldstein in Conservation Maven
If you ever walked along an empty stretch of beach and flushed away a flock of frightened shore birds, you might have wondered to yourself whether you just committed a horrible ecological sin.
Perhaps you asked yourself, "Where are those birds going? Did they just abandon their nestlings? How long until they come back? Or better yet, will they ever come back?"
A new study tries to answer these types of questions with respect to the impact of recreational boaters on nesting colonies of black skimmers in New Jersey where the birds are listed as endangered. As it turns out, the answers can help coastal managers develop scientifically informed regulations such as setting no-entry buffer zones around nesting colonies to minimize human impact....

The impact of vacation homes on bird nest predation
by Rob Goldstein in Conservation Maven
Vacation homes may be harming some birds through increased nest predation, according to the findings in a new study in the journal of European Wildlife Research.
While suburban sprawl receives close scrutiny for its negative environmental impacts, vacation homes and other low density housing in more pristine areas are often overlooked.
However, as Ole-Gunnar Støen and fellow researchers in Norway show, these homes can negatively impact birds by attracting generalist predators that feed on nest eggs.... Read more »
