If you're curious about InVEST I just created a page in "The Inventory" (see link on this page) with some resources and just wanted to hlighlight some potentially interesting models that are worth having a look at!

• Habitat Quality: this model uses habitat quality and rarity as proxies to represent the biodiversity of a landscape, estimating the extent of habitat and vegetation types across a landscape, and their state of degradation.
• Habitat Risk Assessment: this model evaluates risks posed to coastal and marine habitats in terms of exposure to human activities and the habitat-specific consequence of that exposure for delivery of ecosystem services.

• Crop Pollination: this model focuses on wild pollinators providing an ecosystem service. The model estimates insect pollinator nest sites, floral resources, and flight ranges to derive an index of pollinator abundance on each cell on a landscape. If desired, the model can creates an index of the value of these pollinators to agricultural production, and attributes this value back to source cells.
