In their 2012 forest audit report,
American Forestry Management recommended we continue our planting program but to
do so in a different way. They recommended that we should continue to plant trees over the
next 4-5 years but to focus on planting much smaller trees and create more species
diversity that was more drought tolerant. Their thinking was that the forest
will regenerate itself but only within the bounds of the species that exist
today. AFM believed we could improve the heath and drought tolerance of our
urban forest by planting other native species. They cautioned against planting
large trees (30 gal) and focus more on seedlings and 5-15 gallon trees, based
on the fact that these trees are less costly and can survive with much less
watering by man and instead rely on nature.
Last year I thought this was sound
advice and still hold this opinion. What did the Township do in 2013- we ignored
the advice and decided to purchase 1,340- 30 gallon trees, 40% of which have
died. This cost well over $300,000. To me this was "pandering" to those residents that wanted such
trees planted in areas adjacent to their houses. Our action ignored what the
"experts" said was best for our forest and the best use of our money.
Now we are
proposing to repeat this experience abeitedly with only 800 trees but still at
a cost of $134,000. over 50% of the total proposed cost. It is proposed that we can lower the mortality rate and the
wasted money by watering more often. But the proposal still falls well short of
the weekly watering suggested by the Texas Forest Service. Arbor Care, a local
arborist firm, recommends:
- One year old-- For a tree that you can
wrap your hands around its trunk, it needs at least 30-50 gallons of water
every week. In dormant season, water every two weeks
- Two Years old- water every 1-2 weeks all year round
- Mature Trees- water once a month (during a drought, water every 2 weeks).
- Two Years old- water every 1-2 weeks all year round
- Mature Trees- water once a month (during a drought, water every 2 weeks).
Are we prepared to ensure this sort of
watering plan? I think not.
For all of the above reasons I recommend we
eliminate the 30 gallon trees for 2014 and focus only on using the 5 gallon
trees
