Requirements and expectations for citizen scientists  volunteering with TASpeR

Identifying and sampling a red maple (Acer rubrum) tree

The citizen scientists we partner with will collect leaves from a single red maple tree, at peak growing season in August and again when leaves fall from the tree. In order to do this you have to be able to identify a red maple. We are currently putting together a guide on how to identify maple species. In particular, the guide will focus on differentiating red maple (Acer rubrum) from other maples such as silver maple (Acer saccharinum) and sugar maple (Acer saccharum) – stay tuned! For now the USDA has several resources worth checking out: 1) The Plant Database 2) The Plant Guide.

Collecting and recording other relevant data

In addition to providing the leaf samples, citizen scientists will also fill out a form to provide more information about the particular tree and ecosystem from which they sampled.

This additional information will include:

  • Circumference of the tree (to estimate size)
  • Location information (to extract climate and meteorological data from databases)
  • Physical surroundings (street tree vs. yard tree vs. woodlot/forest to inform whether the tree is of cultivated origin)
  • Associated vegetation (to understand the red maple’s vegetative community)

All citizen scientists will be mailed the “TASpeR Measurement Kit” that will include a detailed sampling protocol, materials to collect and store samples, a form to complete on the sampling days, an envelope to send samples back to Boston University, and a sticker with the TASpeR logo!

Who can help out as a citizen scientist?

The TASpeR project is open to any individuals, groups, or teams that are interested! Please get in touch here if you have any questions about eligibility.

Which red maples to sample?

Red maples occur naturally in woodlots and forests, and there is also an industry of cultivated and cloned varieties of red maple sold by nurseries. It is likely that planted street trees and those purchased and planted from landscaping centers are a cultivated variety. The good news is that we are interested in all red maple trees from all environments (urban to rural to forested) in this study – so if you know of a red maple in your area we are interested in it, but do make sure you have permission to sample.

Because this project involves collecting leaf samples from trees and not just making observations, the citizen scientists collecting samples need to make sure appropriate personnel have been contacted to approve the activities prior to collection.  The sign-up form that the citizen scientists fill out will help the TASpeR project leaders identify and assist in cases where it will be necessary to contact relevant authorities to gain sampling permission.
