It's seed collection season! One of the best ways to support the CFRP is by collecting seeds. We are seeking seeds of the following species: white oak (Quercus alba), swamp white oak (Quercus bicolor), burr oak (Quercus macrocarpa), white pine (Pinus strobus), and tupelo/black gum (Nyssa sylvatica).
If you are not sure how to identify these species, there are excellent resources like the free app PlantNet that can help you identify trees based on photographs of the leaves. You can also email images to us at [email protected] for confirmation.
If you are willing to collect but don't know where to go, we can direct you toward places to search.
Seeds are best collected when they are naturally dispersing. For many of these species, now is perfect! Here are some species-specific directions:
Oaks: Collect when the acorns are turning from green to brown and the cap can be easily removed. Best is to collect right off the trees or soon after they fall to the ground. Be gentle with acorns that already have an emerging root. Acorns should be packed into zip-top plastic bags along with a moist paper towel and a twig and leaf for verification of species identity. Keep acorns in the refrigerator until you can send or deliver them to Rice Creek.
Identification tips: all the oak species in our project are in the white oak group, meaning their leaves have rounded lobes, not pointy. Swamp white oak and burr oak leaves are darker green on top and fuzzy and whiter on the bottom. Non-native English oak (Quercus robur) can easily be confused for native white oak and is a common horticultural planting in this area. One distinguishing feature is the rounded, earlobe-like flaps at the base of English oak leaves, while the base of white oak leaves tapers to the stem.
White pine: Pine seeds develop under the scales of pine cones, two per scale. Cones you find on the ground may only have a few seeds left. Seeds can be stored and mailed dry, along with a twig for verification of species identity.
Identification tip: white pine needles are grouped in bundles of 5.
Tupelo/black gum: Fruits are ripe when they turn blue-black. They can be collected directly from trees or off the ground. Fruits can be delivered or mailed as-is to Rice Creek (along with a twig and leaf). Tupelo/black gum trees have oval-shaped glossy leaves that end in a pointy tip. The leaves turn bright shades of orange, red, and purple in autumn. This tree naturally grows in moist sites but is also planted as a street tree.
Please include your contact information and the collection location (as specific as possible) when you mail or drop off your seeds. Our mailing address is: Rice Creek Field Station, SUNY Oswego, 1020 State Route 104, Oswego, NY, 13126. Seeds can also be dropped off Monday through Friday, from 9 am to 4:30 pm, or Saturday 9 am to 3 pm.
