Each year, governments spend billions of dollars globally to incentivize wildlife-friendly farming and other agri-environment schemes (Donald and Evans 2006), though limited information exists on where to target such financial incentives to maximize biodiversity benefits, potentially leading to the haphazard allocation of resources (Polasky et al 2008;Kremen and Merenlender 2018).…”

Depending on management practices, agricultural lands can either pose substantial barriers to the movement of native species or can support landscape connectivity by linking areas of high-quality habitat. Balancing connectivity and sustainable food production on agricultural lands is critical to conservation in the conterminous United States (CONUS) where agriculture makes up close to half of total land area. However, limited guidance exists on where to target conservation resources to maximize benefits for native species and food security. To quantify the potential contribution of agricultural lands to the movement of organisms, we developed a novel method for estimating agricultural management intensity (based on remotely sensed temporal variation in vegetation cover on croplands and pastures) and incorporated these estimates into a CONUS-wide, circuit-theory based model of ecological flow connectivity. We then combined our connectivity results with data on the productivity, versatility, and resilience of agricultural lands (PVR) to identify conservation opportunities that support both biodiversity and food production. The highest levels of connectivity on agricultural lands occurred on relatively unmodified rangelands and on cropland and pasture in close proximity to large amounts of natural land cover. Mapping connectivity and PVR across CONUS revealed 10.2 Mha of agricultural lands (2.7%) with high value for both connectivity and food production, as well as large amounts of agricultural land (>140 Mha in total) with high value for either cultivation or supporting biodiversity (e.g., through ecological restoration). Drawing on these findings, we provide recommendations on the types of conservation approaches most suitable for a given agricultural system and link these recommendations to specific government incentive programs. To help facilitate conservation planning based on our results, we have developed an interactive web application, allowing users to visualize the spatial data developed here within their regions of interest.

“…This is in line with studies arguing that habitats with greater plant diversity encourages the growth and activity of natural enemies (Hussain et al 2021;Letourneau et al 2021). Even though the predictions made by these studies are frequently observed in agricultural systems(Landis et al 2000;Maas et al 2021), it has rarely been considered for green roofs. This study results indicate that, for six observed insect taxa groups, the resources provided by a diverse plant community in nearby public gardens might be more relevant(Schunko et al 2021), as many generalist insect species can thrive in small habitat of nearby green roofs.…”

Rapid urbanization is among the factors, causing decrease in insect diversity. However, by offering suitable habitat, green roofs could lessen such adverse effects of urbanization. Certain factors, like a nearby public garden could be useful predictor variables to analyze at what extent green roofs can support insect communities. The aim of the study was to measure the insect diversity on intensive green roofs located close to public gardens, and more isolated green roofs within an urban setting. Insect species richness, abundance and assemblages were different on the green roofs close to public gardens compared to isolated green roofs. We can conclude that green roofs near a public garden will host more species, especially pollinators, consequently lessens urbanization's negative effect. Establishing a green roof at the right location would probably enhance biodiversity conservation in an urban setting. To properly understand how landscape factors impact insect communities on green roofs, future studies on green roofs should take public gardens into consideration.

Land use change is a major driver of pollinator decline and loss of pollination services. For plant and pollinator interactions to persist in rapidly changing urban systems, co‐occurring species must share matching traits, including phenological, morphological, and physiological traits. Thus, the knowledge of trait matching among interacting plants and pollinators can aid in the design of pollinator habitats and enhance the conservation value of urban green spaces, but this remains relatively understudied. Here, we review how trait matching facilitates the persistence of interactions and creation of new interactions in urban plant–pollinator networks. We highlight four major urban drivers facilitating the restructuring of plant–pollinator networks through species loss and gain in urban areas. We also show different pathways by which the matching of morphological, phenological, and physiological traits of interacting plants and pollinators is affected by urbanization. Furthermore, we show how the knowledge of functional traits can help to predict novel plant–pollinator interactions in urban environments, including those among exotic species. Finally, we show how the application of trait matching can aid management practices, facilitating the design and creation of sustainable green spaces that will accommodate functionally diverse pollinators and plants within the urban matrix.
