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.

Greening of Seattles Paramount Theater
Seattle is a pretty green city, both in vegetation and environmental awareness (although the lack of public transportation situation is mind boggling), so it is only fitting that one of the most recognizable entertainment icons is getting a green revamp. The Paramount Theater near the heart of downtown Seattle is in the process of a green upgrade, starting with the signature marque sign.
The newly replicated sign will be approximately 90% more energy efficient. Currently The Paramount vertical sign has 1,932 incandescent bulbs using 11 watts per bulb, driven by several large mechanical chasers. The replacement consists of .75 watt LED bulbs with electrical chasers gaining the largest energy efficiency increase. Magnetic transformers will be replaced with Ventex High Power Factor (HPF) electronic transformers to power the neon portions of the sign. These units will save up to 66% of the energy currently being consumed by the neon lights.
