Journal Entry Week 4

February 13, 2013
Week 4
Work Hrs: 7 Total Hrs: 28
Week 4
        Today was interesting, fun, long, and most of all very productive. It was filled with multiple tasks and projects. The morning began working with the Wednesday crew along side the Younger Lagoon ridding an area of invasive hemlock or Conium maculatum. The hemlock is growing in a rather large patch trail side under a small grove of California buckeye trees or Aesculus californica. Also growing amidst the hemlock was a native rose species Rosa californica. To get the hemlock under control, we used a technique called tarping or soil solarization. This technique works in eliminating invasive exotics or 'weeds' by exposing them to the least optimum growing conditions. As the name soil solariztion infers, by covering the affected area with a strongly woven black tarp, it harnesses natural solar radiation to elevate temperatures. The other main objective of a black tarp is to block out precious sunlight used by weed seedlings to convert to photosynthesis and thus grow into adults. The hope is to eradicate all weeds currently growing as well as wipe out future progeny's from eradicating the entire seed bank.

I spent the afternoon taking full advantage working solo. It really gives me a chance to observe my natural surroundings. I toured the grounds taking my weekly well readings and checking out white-tailed-hawks, red-tailed hawks and herons. Trying to be efficient, I also packed my backpack full of tools to replace broken wooden stakes holding up chicken-wire fencing surrounding smaller research plots located in the main field area. My last task consisted of mending a hole in the upper fence provided to keep the public out of the lagoon areas. I  turned a weak spot in the armour into an impenetrable fortress.(Sorry surfer dudes.)
