UNEPs World Environment Day – June 5
The United Nations Environment Programme is holding the World Environment Day on June 5th with the theme: Forests: Nature at Your Service. What began in 1972 has spread worldwide into an international day of action for the environment.
It has also been declared the International Year of Forests to highlight the importance of this natural resource. In decline worldwide, we depend on forests to combat climate change and provide water, shelter, habitat and support life on our planet.
Trees, Habitat Restoration and Arbor Day
Arbor day brings mixed feelings for me, which may sound strange because who doesn’t like trees? Having worked some time as a restoration ecologist, I may be privy to the dark secrets of habitat restoration or ‘enhancement’, that many well-meaning charities and non-profits may be unaware of: Nature heals itself! Be sure you look into where your trees are being planted this Arbor Day, here is what to look for:
Restoration of Existing Habitat – BAD
I have seen many groups attempting to restore National Parks, and wildlands after natural disasters such as fires, landslides and the like, which just makes me cringe. If the area is within a protected habitat and has just been devastated by a natural disaster, the best thing you can do is leave it alone. A restoration attempt in these areas will only introduce non-native and invasive species (usually carried in by the restoration crews in their shoes, clothes, automobiles and equipment). It can further disturb and disrupt the natural environment, causing more damage and long-term affects.
Restoration of Human-Impacted Habitat – GOOD
What is in need of restoration, are the habitats degraded by human activity such as farming, grazing and building. These areas have usually been so disturbed, damaged, or inundated with invasive species that it is unable to recover on its own. Fallow fields, urban lots, intensive agriculture and pastures are all good examples. Restoration is a difficult task and requires › Continue reading

Continued from Part I of Seeing the Forest for the Trees.
Last week I attended Dr. Peterson’s lecture, “Climate, Forests and Future: A View from Treeline” at the University of Washington as a part of the School of Forest Resources and the College of the Environment lecture series, Sustaining our Northwest World.
There were two subjects within the lecture that particularly caught my attention, the first being a number of actions that policy makers and environmental managers need to take into account when preparing for the effects of climate change. The second topic was a discussion on the very interaction of climate scientists and policy makers themselves and the effects on the issues at stake. He said that scientists as well as environmental managers need to take a keep a number of things in mind when responding to this climate crisis. › Continue reading

Last Thursday evening I attended the public lecture “Climate, Forests and Future: A View from Treeline” by Dr. Dave Peterson – forest service scientist, professor and co-nobel prize winner. He spoke at the University of Washington as a part of the School of Forest Resources and the College of the Environment lecture series, Sustaining our Northwest World.
Initially his talk focused on the ecological aspects of the local climate change impacts in the Pacific Northwest, such as a projected increase in mountain pine beetle population that has already caused havoc in British Columbia. The beetle infestation will result in an increase in surface fuel and eventual forest fires. Washington, Oregon and Idaho forests are already beginning to see these effects of climate change.
Dr. Peterson continued on to discuss two topics that particularly caught my interest, the first being how exactly to prepare and respond to the effects of a climate change that we are already experiencing? Because essentially, that is the point we have reached. We are already seeing and experiencing the local effects of increased green house gases in our atmosphere. Now, we need to recognize this and begin to focus on how best to react to those changes, effectively. It’s no longer a question of if… it’s a question of when and how.
He outlined a number of actions that every policy maker and environmental manager should take to heart at this point, particularly those in the forest service though they are applicable across the board. › Continue reading
