SCBI tree mortality

Sampling location

SCBI ForestGEO plot

Sampling dates

2014- 2019

Protocols

The basic census is described in Gonzalez-Akre et al. (2016). This covers all methods used in 2014 and 2015.

Since 2016, we started monitoring all ash tress (Fraxinus spp.) stems down to 1cm DBH in order to capture dynamics of emerald ash borer infestation. The protocols for 2018 and 2019 (with a small modification from the original) are available here

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 rot 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 is here.

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 our trees is given here.

Data use

2014 and 2015 mortality census data used in Gonzalez-Akre et al. 2016 are published in Dryad and may be used as detailed in the metadata of this publication, as may updated versions of those datasets in this repository.

Data from 2016-2019 censuses are currently being used in analyses and may not be used without permission of the PI (Kristina Anderson-Teixeira). We welcome inquiries about potential collaboration.
