Drought Stress Affects More Species
During a visit today I noticed the effects of the current drought.
Months of high temperatures, lack of rainfall and moisture-sucking winds have taken their toll.
None of this year's crop of Scrub Lupine seedlings appear to have survived. Only a handful were still alive when I checked earlier this month.
However, the effect is visible in established adult plants of other species.
Today I observed brown foliage on Bonamia grandiflora, Persea humilis and Polygonella myriophylla.
In addition I saw only a handful of butterflies, which is unusual for this time of year.
The plants will certainly survive, just as they did in previous droughts, I suppose.
The last serious dry spell to hit the area was in the 1998-2000 period, which is before this was state property. so I don't know what happened.
When I first visited the site in 2002, everything appeared healthy, thanks to the resumption of normal rainfall.
