Experimental wood falls were deployed in May 2017: 11 Pinus elliotti and 12 Celtis laevigata. Trees were fresh cut and logs dried to a moisture of ~15%. Logs were sewn into a synthetic fiber mesh bag to enable subsequent collection of highly degraded wood falls (5 mm mesh, ensuring larval settlement was not hindered). At each site, wood falls were dispersed ~5m apart. Wood falls were collected in February of 2019 after 21 months. Wood falls were immediately preserved in 80% ETOH and all macroinvertebrates subsequently removed and identified. Originally entered coordinates (27.13499, -89.92435) synonymized with WF1 official coordinates.
