The role of vacant lots in promoting avian species diversity and occupancy in a post-industrial city.
Article in Landscape and urban planning, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In deindustrialized cities, human population decline and building demolitions have created large quantities of vacant land. Land vacancy is a complex social issue but may create habitat that supports wildlife. We explored the relationship between vacant land and other features of the urban landscape and bird diversity and occupancy in Detroit, Michigan. Acoustic recordings were collected annually in June at 110 sites across 11 Detroit neighbourhoods from 2021 to 2024. At each site we manually scanned 28 min of the morning chorus on two days to identify bird species. We compared resulting metrics of species diversity and occupancy with annual spatial data on neighbourhood characteristics including vacancy, vegetation, buildings, and roads measured in 50 m and 100 m buffers around each recording site. Using a mixed-effects modelling approach, we found higher bird species diversity and richness at recording sites surrounded by greater proportions of vacant land (Shannon diversity, β
