Earlier this season as we were getting ready for a new quarter of restoration work in the Union Bay Natural Area, a friend supplied me with her wonderful collection of photographs from the 2004 planting of UBNA’s “blue tube forest”.  It was a pleasure to be given a look back in time to the beginning of this project, as I have only been familiar with UBNA for a mere 2 years.  During the 2004 project, students planted over 1,000 bare root trees into what was then a grassy field, mulched these new seedlings, and protected them with blue plastic planting tubes.  Today, as anyone who strolls along Wahkiakum Lane well knows, that area is certainly not a grassy field any more!

In addition to the planting, students also participated in a Native American ceremony to bring the bald eagles back to UBNA; an effort whose success our birding friends can attest to.

Let’s have a look back to 2004:

Walking through UBNA today, one notices many of these once tiny cherry, poplar, ash, willow, and alder seedlings have matured into healthy saplings, filling in the canopy of this new woodland.  In more recent years, the overall diversity has been increased with supplemental plantings of conifer species such as western red cedar and Douglas fir.

Unfortunately the woodland restoration plot has also been impacted by invasive Himalayan blackberry, which competes with the desired woodland species for important resources and threatens the overall health of this newly established ecosystem.  This invasion has been consistently managed over the years and will remain a perennial effort until the canopy is mature enough to cast shade over the blackberry plants, bringing them under a natural control.

Fortunately, UBNA has many friends in both the UW community and the general public who have given their time over the years to help nurture this newly established woodland, and 2011 has been no different!  During the winter quarter there have already been 3 volunteer work parties, with several more scheduled throughout the rest of the academic year.

If these efforts sound intriguing, you too can join the efforts to create healthy native ecosystems in the Union Bay Natural Area.  For info on upcoming volunteer work parties, have a look at the UWBG’s volunteer calendar and register for an upcoming event.  You’re guaranteed to leave feeling a sense of accomplishment, and you may even see a bald eagle!
