In the first attempt of its kind in Idaho, IDL (in cooperation with local governments) has applied for a grant from the US Forest Service to develop and implement a GIS analysis, using CityGreen software and high-resolution satellite imagery of tree canopy to address stormwater mitigation and water conservation and quality in both developed and rapidly developing areas of Kootenai County, Idaho, an area of approximately 100 square miles.
And Bill Belknap reports that Moscow's Tree Commission is "working on a similar study and model for the City of Moscow. The have a group of Americorps volunteers that will be working on updating the City’s TreeWorks GIS public tree inventory system and then integrating it with the CityGreen to model and quantify the environmental and economic benefits of the urban/community forest. It appears that they may have their findings back in time to incorporate within the Comprehensive Plan revision."
Being a fan of the urban forest for its beautiful lumber and the trees for their carbon sequestration value, I'm interested to hear that serious effort is going into understanding their role in watershed management. I hope this information moves forward fast enough to provide guidance to the new comprehensive planning effort.
