Habitat edges decrease plant reproductive output in fragmented landscapes

Habitat loss is a major threat to biodiversity, but effects of habitat fragmentation are less clear. Examining drivers of key demographic processes, such as reproduction, will clarify species-level responses to fragmentation and broader effects on biodiversity. Yet, understanding how fragmentation affects demography has been challenging due to the many ways landscapes are altered by co-occurring habitat loss and fragmentation, coupled with the rarity of experiments to disentangle these effects. 
In a large, replicated fragmentation experiment with open savanna habitats surrounded by pine plantation forests, we tested the effects of inter-patch connectivity, patch edge-to-area ratio, and within-patch distance from an edge on plant reproductive output. Using five experimentally planted species of restoration interest – three wind-pollinated grass species and two insect-pollinated forb species – we measured plant flowering, pollination rate, and seed production.

## Description of the data and file structure

Data collected from experimentally fragmented landscapes at the Savannah River Site. Five plant species were experimentally planted at varying distances from the edge. Reproductive status, flowering, and seed production were recorded for each individual.
