Designing effective habitat and protected area networks, which sustain species-rich communities is a critical conservation challenge. Recent decades have witnessed the emergence of new computational methods for analyzing and prioritizing the connectivity needs of multiple species. We argue that the goal of prioritizing habitat for multispecies connectivity should be focused on long-term persistence of a set of species in a landscape or seascape. Here we present a review of the literature based on 77 papers published between 2010 and 2020, in which we assess the current state and recent advances in multispecies connectivity analysis in terrestrial ecosystems. We summarize the four most employed analytical methods, compare their data requirements, and provide an overview of studies comparing results from multiple methods. We explicitly look at approaches for integrating multiple species considerations into reserve design and identify novel approaches being developed to overcome computational and theoretical challenges posed by multispecies connectivity analyses. There is a lack of common metrics for multispecies connectivity. We suggest the index of metapopulation capacity as one metric by which to assess and compare the effectiveness of proposed network designs. We conclude that, while advances have been made over the past decade, the field remains nascent by its ability to integrate multiple species interactions into analytical approaches to connectivity. Furthermore, the field is hampered its ability to provide robust connectivity assessments for lack of a clear definition and goal for multispecies connectivity conservation.

Climate change is reshaping urban environments, intensifying the need for resilient green space design and management that supports biodiversity, improves ecosystem services, and adapts to changing conditions. Understanding the trade-offs between native and non-native species selection is important for developing climate-resilient urban green spaces. This review examines public preferences for native versus non-native plant species and their implications for urban green space design and management. We critically analyse the ecosystem services and biodiversity benefits provided by both native and non-native plants in urban spaces, highlighting the complex trade-offs involved. Our findings indicate that while native plants can be underrepresented in urban landscapes, they offer significant ecological benefits including support for local wildlife and pollinators. Some studies have highlighted the climate resilience of native plants; however, they are likely to be more affected by climate change. Therefore, conservation strategies are needed, especially for endemic and threatened plant species. Several studies suggest a more flexible approach that integrates plant species from diverse climatic origins to improve resilience. We also explore conservation gardening (CG) as a socio-ecological strategy to integrate endangered native species into urban landscapes, promoting biodiversity and ecosystem resilience. This review stresses the importance of informed plant species selection and community involvement in creating climate-resilient urban green spaces.

Direct tree seeding is potentially an economical technique for restoring forests on abandoned fields. However, the success of tree establishment depends on many factors related to species and seed characteristics, environmental conditions, competition and predation. We compared seedling emergence, survival and growth of six tree species of different seed sizes in a forest restoration project of abandoned fields. Species were seeded in plots with and without herbaceous vegetation and with and without protection from bird and mammal predation. Yellow birch (Betula alleghaniensis) did not emerge in all treatments, paper birch (Betula papyrifera) and tamarack (Larix laricina) had a seedling emergence rate lower than 1%, and sugar maple (Acer saccharum) had a low overall emergence rate of 6%. Seedling emergence reached 57% for northern red oak (Quercus rubra) and 34% for red pine (Pinus resinosa), but survival of oak after one year was much higher (92%) than pine seedlings (16%). Overall, protection from birds and mammals and elimination of the herbaceous vegetation cover had no detectable effects on seedling emergence, survival and height. Nonetheless, red oak seedlings growing in the presence of vegetation had a smaller diameter and shoot biomass and a larger specific leaf area. We conclude that only large seeded species, such as oak, should be used for forest restoration of abandoned fields by direct seeding in our region.
