    From the Boston Globe: The City Is an Ecosystem

    | Research
    November 17, 2014
    The city is an ecosystem, pipes and all What scientists are finding when they treat the urban landscape as an evolving environment of its own By Courtney Humphries Boston Globe Correspondent November 07, 2014 Is a tree trying to survive in the city better off than a tree growing in the forest? The obvious answer would seem to be “no”: City trees face pollution, poor soil, and a root system disrupted by asphalt and pipes. But when ecologists at Boston University took core samples from trees around Eastern Massachusetts, they found a surprise: Boston street trees grow twice as fast...

    Silence Isn’t Golden

    | Advocacy, Network, Research, Resources
    April 14, 2014
    Over the next month, community groups and ReLeaf Network members across California have an opportunity to comment on two important issues. They are the Department of Water Resources’ (DWR) Integrated Regional Water Management Plan (IRWM); and the California Air Resources Board’s (CARB) Urban Forest Project Protocols. To date, these efforts have been fairly non-profitable for urban forestry groups working daily to green our golden state, but with guidance from stakeholders they could prove to be beneficial.   In March, 2014, Governor Brown and the Legislature directed DWR to expedite the solicitation and award of $200 million in IRWM funding to...

    Preserving Trees Through Climate Change

    | Research
    November 15, 2013
    ASU researchers studying how to preserve tree species amid climate change     TEMPE, Ariz. — Two researchers at Arizona State University are aiming to help officials manage trees based on how different types are affected by climate change.   Janet Franklin, a geography professor, and Pep Serra-Diaz, a postdoctoral researcher, are using computer models to study how quickly a tree species and its habitat will be exposed to climate change. That information is used to locate areas with specific elevations and latitudes where trees could survive and repopulate.   “This is information that would hopefully be useful to foresters,...
