As part of my PhD, I want to predict when lodgepole pine releases pollen and when its seed cones are receptive across as much of the species range as I can. I’m using data collected in seed orchards (thanks Joe Webber, Chris Walsh, Rita Wagner, and the countless people who were part of building these data sets) to build a model, and I’d like to use citizen science data from the National Phenology Network to test my model.
Right now, the dataset for lodgepole pine from NPN has observations for 28 individuals at 6 sites over about 2 months in 2 years. I’d like more sites, more individuals, and more years to test my model against. I’m going to be tracking down as many lodgepole pine populations as I can around Vancouver and keeping track of them in my own Nature’s Notebook.
You could help!
NPN has pretty fantastic data sets from a lot of awesome volunteers. You can be awesome, too: pick your favorite species and start collecting data! It will make you look really important when you’re out hiking and provides a great excuse for that time your neighbor catches you in their yard right next to their lovely camellias.
Of course, I hope all you western North Americans choose to start collecting data on lodgepole pine. How could you resist these lovely little pollen cones?

If you’ve never had a close look at pollen cones, here are some nice pictures summarizing the stages the cones go through from a report by John Owens:1
Figure from Owens 2006.
If you give me a year and a location, I want to be able to tell you when stages 3 and 4 happened. Stay tuned for results!

I love that “phenology” is becoming a household word– but not why!
Those are indeed lovely pollen cones.
