The official travel blog of Natural Habitat Adventures/WWF with a nice summary of the utility of corvid seed dispersal to habitat restoration.

Here is the third paper from my dissertation work, which is probably my favorite. Using more than 200 hours of observation, and with more than 800 caching observations, we show that seed dispersal rates and distances vary with acorn crop, and dispersal rates with territorial aggression. This has major implications for the role of masting behavior by trees, that affects seed dispersal directly, but also indirectly via social interactions that ultimately depend on population density which is driven by acorn crop.
