Re: 25,000 bumblebees killed, dropping from trees in Wilsonville; pesticide suspected
Yankee, IN the second photo there is in fact approx 500 bees in the one parking space alone. with 50 trees and that number representing only one side of the tree the number is likely to be more like 50,000 bees. It's called math and it was developed in order to count large numbers in cases just like this. I am sure it is all fine and good if the number was only 24,999 though.
Blue Diamond. You claim time and again that this kill is not that significant given the rate of kill urbanization makes. then claim that these numbers in fact being present in a parking lot is proof that urbanization is not harming the bees. so which is it. the kill does not mater because it is insignificant. or is it?
I say for a fact that I see dead bees under a tree. urbanization had not harmed these bees. the pesticide sprayed on the trees did. No car ran into them. they where not starving to death they where poisoned by use of a chemical inconsistent with it's labeling. In horrific numbers. This is not the result of over half a million cars passing by. this was the result of one person with a sprayer. this is not the result of housing and development for thousands of people. this is the result of lax care of decorative foliage in a single location.
You cannot in any way describe what actually has happened in this case and call it okay you have to change nearly every detail of what in fact happened.
It is not really thousands of bees but hundreds so that is fine. except it is thousands. It is fine because many more bees are killed by cars. I have not seen a high incident of trees being planted in the middle of freeways or cars passing through target parking lots at a speed high enough to kill many bees. I actually suspect more bees die from natural causes than any other reason.
I keep bees in the middle of a city and can tell you first hand bees do just fine there. they do better in this area with it's abundant artificially maintained landscape.
It also does not require much more than a casual observation to realize that bees will favor a specific forage at specific times. it is most likely these bees are victim of unfortunate timing. I know of one type of bush a couple of blocks from my house. If pretty much anything else is on bloom you will not see a bee one on these bushes even though it is constantly in bloom. but let a dearth hit for even a couple of days. and they are crawling with bees. I have come to call them the robber trees. If I see bees foraging on them I know that bees are hard up for finding anything to forage on. Unlike lavender that will attract bees no matter what else is in bloom. I suspect that these trees where something that attracted the bees in huge numbers. so well in fact that in attracted and consequently killed every bumble bee in the area for several miles. So yes I agree the bumble bee population was just fine in this area. Until it was killed by this one application of pesticide.

Significant Minority vs Insignificant Majority, 20% of causes produce 80% of the effects.
