Hi Paul & All, June 14, 2013
Based on my dim recollection of Elementary Botany, I doubt that =
pollen contributes materially to the nitrogen cycle, or any nutrient =
cycle, with the obvious exception of insects or other animals that feed =
directly on pollen as or before it is shed.=20
That being said, nutrients will always flow from nutrient-rich areas =
to nutrient-poor areas but the pollen component will be tiny compared to =
such media as bird droppings, seeds carried by wind, water or animals, =
leaves and movement of animals, passive or active.

Subject: Re: [NatureNS] pollen from which tree
Hi Nancy and All
All conifer trees produce copious amounts of pollen.
As some have suggested White Pine is one of the main producers here
but hemlock, fir and spruce do also. One of the reasons old growth =
forests
are so important to the health of the area.
My best pollen story was a number of years ago, my daughter was =
studying
geology - she came home one day and said Dad - I want you to show me a =
hemlock tree.
I know what million year old hemlock pollen looks like from the rocks =
we study
but not the tree! The question was solved looking out the window.
The reason pollen is so important it is a key link in the Nitrogen =
Cycle. A long time since
I studied that and I forgot the formulas as soon as I passed the =
course. Some of my friends
remembered them longer as they had to repeat the course!
Pollen as you say falls in the water and it provides food for the =
small things, nymphs and other
life forms. Small things feed bigger things and after awhile the =
nitrogen in the pollen ends up
in fish, loons, turtles and so on. Some might even end up in my frying =
pan.
As the story in the Bible, it is really manna from heaven for Nature =
in NS!
Enjoy the spring
Paul

Subject: [NatureNS] pollen from which tree
Which species of tree is dispersing the pollen seen now on lakes in =
the SW half of NS? Pine?
This photo shows an area of sheltered shoreline on L Torment, E =
Dalhousie, Kings Co where the wind has gathered the pollen into electric =
green windrows. It is more thinly dispersed throughout the lake but =
still easily visible from a boat as a green suspension just below the =
surface.
