We get cedar pollen at our pond. It's bright green and grainy and floats.
We found two methods work to remove cedar pollen:
1. Make a make shift net (we used old fabric) and skim the pollen from the surface of the pond. This takes a long time and is labor intensive. However if enough adult beverages are consumed during the process it can become quite amusing. We found the best method was to wait until wind blew the pollen to one corner of the pond and net the heck out of it.
2. Wait for nature to take it's course and eventually it will go away.
Unfortunately, pollen removal has been found to be harmful to the Quino Checkerspot Butterfly. Restoration of the glassy, mirror-like surface causes the butterflies to try to mate with their reflections, resulting in unacceptable mortality by drowning. The proper authorities have been notified, and are even now planning to drain the offending BOW and replant the space with buttercups.
Any loss of GSF which might occur is of course completely unintended.
