2014- present (annually)
The basic census is described in Gonzalez-Akre et al. (2016). This publication covers methods used in 2014 and 2015. From 2016-2023, we monitored all ash tress (Fraxinus spp.) with stems >1cm DBH in order to capture dynamics of the Emerald Ash Borer (EAB) infestation. For updated methods please check this folder.
We have collected cores from many of the trees found dead in our censuses. In 2016-2017, all trees found dead in 2016 and 2017 were cored at breast height (1.3 m) and at base (~30 cm form ground) except if trees where extremely rotten or if other hazards prevented boring or resulted in a very poor quality core. Since 2018 we have reduced the number of cores taken from dead trees as we have good chronologies for multiple species and to avoid additional work from our field technicians. Tree core data can be found here.
Numbers of trees and species cored since 2017 is as follows:
- 2016 - all trees found dead
- 2017 - all trees found dead
- 2018 - 24 cores, 7 sp
- 2019 - 51 cores, 19 sp
- 2020 - 68 cores, 15 sp
- 2021 -
- 2022 - no cores collected
- 2023 - no cores collected
- 2024 - no cores collected
As a resut of our annual surveys, We have been paying increasing attention to signs of insect pests and pathogens on newly dead and unhealthy trees. A list of pests and pathogens that may affect trees at the SCBI plot is given here.

Data are published to this reposity immediately upon collection. We require that the (mostly early-career) members of our team who contributed to data collection be given the opportunity to contribute as coauthors (with full opportunity to comment on analysis plans and draft manuscripts) to the first scientific publication using the data. Data usage agreements therefore depend upon collection date, currently deliniated as specified below.

These data are covered by a custom data use agreement. Please refer to the data_use_agreement.md file for details. Data use requests may be denied if they compete with planned publications (particularly those led by early-career researchers) or fail to adhere to acceptable standards of scientific integrity and rigour. We strongly advise contacting PI Kristina Anderson-Texeira prior to beginning analysis of these data.
