Tiny catkins, massive pollen mission
๐พ These are the staminate catkins, the male flowers of bear oak (Quercus ilicifolia), documented this past Monday during our Intro to Monitoring session on phenology. The ribbed reddish structures are the anthers of the male catkins, now fully exposed and beginning to dehisce, opening to release pollen into the spring air.
Not all flowers are synchronized. Some anthers are just beginning to open, while others have already started to empty. That staggered timing extends the pollen dispersal window, an elegant strategy for a wind pollinated tree navigating the unpredictability of spring conditions.
It is a fleeting stage, easy to overlook, yet essential to the reproductive pulse of the oak forest.
Check out this week's phenology of this bear oak for more details and you’ll also see its beautiful female flowers. I shall talk about those beauties another time ๐
