Do early-successional weeds facilitate or compete with seedlings in forest restoration? Disentangling abiotic vs. biotic factors

Census data for seedlings part of a weed exclusion experiment at Sal del Rey, Texas within a larger field where ~100,000 seedlings were planted in October-November 2018. Records seedling height, vigor (0 - dead, > 0 - alive), branching, and animal damage for 158 individuals of eight species classified by growth habit (fast/slow) and distributed in control and exclusion (mowed) plots across seven censuses.
