The weather didn’t cooperate for our last fall volunteer workday on December 7. The temperature was in the low 40s, and just at 10 a.m. when the workday was beginning, it started raining and didn’t quit until the workday was over. Brrrrr! Nonetheless, a great team of dedicated volunteers, including a large contingent of students […]

Because the BFS ‘Neck’ is long and skinny, with a lot of “edge” relative to its area, non-native ornamental plants have entered the Neck from adjacent yards, and at last Saturday’s workday, volunteers removed a number of these invading plants from the lower part of the Neck. One target was a sizeable stand of Century […]

Cutting back Cattails

Conjure up a mental image of pHake Lake, and what do you see? Cattails! As shown nicely in the title image for this blog, a ring of Broad-leaved Cattails (Typha latifolia) almost completely encircles the lake. Broad-leaved Cattails are native to California, and the BFS they provide habitat for some of our resident native animals, […]

Oct. 5 workday canceled!

Because of very low humidity and strong Santa Ana winds, the National Weather Service has issued a “Red Flag Warning” for extreme fire danger for LA County and surrounding regions. We have consequently been asked to curtail all activities at the BFS for the next few days. As a result, the BFS volunteer workday scheduled […]

BFS volunteer workdays resumed last Saturday, when the volunteer crew cleared brush around the old infirmary as to reduce the fire hazard. The very dry year (2013 precipitation so far is less than half of average) and extensive reporting on several large wildfires (including the Rim Fire near Yosemite and the Yarnell Hill Fire, which […]

Star Thistle finale

This academic year’s last two volunteer workdays on June 1 and 15 were devoted to finishing off the Maltese Star Thistles (Centaurea melitensis aka Tocalote). As previously discussed, Maltese Star Thistles are one of our most problematic invasive plants at the BFS. We’ve continued our strategy of having large infestations in open areas cleared with […]

Star-thistle time again

It’s now that time of year when the Italian Thistles (Carduus pycnocephalus) have gone to seed, so the volunteers have turned their attention to Maltese Star Thistles (Centaurea melitensis, aka Tocalote), which are starting to bloom. You can read about these invasive thistles and our overall Star Thistle management strategy in this post from last […]

Adieu, Italian Thistles

At the May 4 workday volunteers continued removing Italian Thistles from the west side of the lake berm and the area surrounding the “toad pond mound”. This was our last Italian Thistle removal for the season. We’ve treated the most the major infested areas, and it’s time to turn our attention to Maltese Star Thistles, […]

Transformation of the toad pond mound

Some time in the past, perhaps in the early 1970s, a very large mound of dirt was dumped on what is now the southwestern portion of the BFS in preparation for a development that never happened. Because the dirt in the mound has more clay than the native BFS soil, it retains more water, and […]

Mustard and thistle removal continues…

Last Saturday volunteers continued our campaign to control invasive annual weeds, starting with a newly discovered patch of Sahara Mustard (Brassica tournefortii) growing behind the old infirmary. Unfortunately, the mustard had already set seed, but the plants we removed had a lot of unopened seed pods, so we were able to keep most of the […]
