With benefits to both human well-being and pro-nature conservation behaviors, nature connectedness is emerging as an important psychological construct for a sustainable future. The growing research and applied and policy-related interests require a straightforward measure of nature connectedness that is suitable for both children and adult populations. To establish the reliability of the new Nature Connection Index (NCI) three factor analyses were conducted. One was based on a large Monitor of Engagement with the Natural Environment (MENE) dataset for adults (n = 3568) with a replication from data sets collected online (n = 553), and a third used MENE data from children (n = 351). To validate the NCI as a measure for nature connectedness an online comparison study (n = 153) included the NCI alongside other established measures. The results showed that the NCI was a reliable and valid scale that offers a short, simple alternative to other measures of nature connectedness, particularly for populations including both children and adults, measured face to face or online. The utility of the NCI is also supported, with variations associated with various pro-environmental and pro-conservation behaviors observed, and importantly the NCI also revealed changes in nature connectedness across the lifespan.

The biodiversity crisis demands greater engagement in pro‐nature conservation behaviours. Research has examined factors which account for general pro‐environmental behaviour; that is, behaviour geared to minimizing one's impact on the environment. Yet, a dearth of research exists examining factors that account for pro‐nature conservation behaviour specifically—behaviour that directly and actively supports conservation of biodiversity. This study is the first of its kind to use a validated scale of pro‐nature conservation behaviour. Using online data from a United Kingdom population survey of 1,298 adults (16+ years), we examined factors (composed of nine variable‐blocks of items) that accounted for pro‐nature conservation behaviour. These were: individual characteristics (demographics, nature connectedness), nature experiences (time spent in nature, engaging with nature through simple activities, indirect engagement with nature), knowledge and attitudes (knowledge/study of nature, valuing and concern for nature) and pro‐environmental behaviour. Together, these explained 70% of the variation in people's actions for nature. Importantly, in a linear regression examining the relative importance of these variables to the prediction of pro‐nature conservation behaviour, time in nature did not emerge as significant. Engaging in simple nature activities (which is related to nature connectedness) emerged as the largest significant contributor to pro‐nature conservation behaviour. Commonality analysis revealed that variables worked together, with nature connectedness and engagement in simple activities being involved in the largest portion of explained variance. Overall, findings from the current study reinforce the critical role that having a close relationship with nature through simple everyday engagement plays in pro‐nature conservation behaviour.

Scientists have classed the ongoing decline in biodiversity—caused by humans—as a mass extinction. To mitigate the consequences of this extinction, immediate action is of the utmost importance. However, effective ways of promoting pro-nature conservation behaviours to preserve and enhance biodiversity require better understanding and measurement. Thus, a reliable and valid measurement tool is needed. While there are measurement tools for general pro-environmental behaviours, as of yet, no measure of behaviours that specifically promote biodiversity exists. Here, we present such a tool: the Pro-Nature Conservation Behaviour Scale (ProCoBS), a psychometrically validated questionnaire scale measuring active behaviours that specifically support the conservation of biodiversity. An item pool developed through consultation with wildlife and biodiversity experts was subjected to psychometric scale development analyses. Data from 300 participants were used to develop the 18-item ProCoBS long form, as well as an 8-item short form. A latent variable model with four factors (Individual Engagement, Social Engagement, Planting, and Wildlife) was identified. In a second study, a subset of 250 of the original participants answered the questionnaire again, in addition to related psychological constructs. The data were used to assess test–retest reliability and construct validity. Results showed that the scale and its short form were reliable (full scale: α = 0.893, short form: α = 0.825) and valid. In a third study, a representative sample of 1298 adults in the UK completed the short form. Confirmatory Factor Analysis demonstrated a good fit for all factors, indicating that the ProCoBS is a psychometrically robust measure. The ProCoBS provides the definitive, much needed tool for measuring conservation behaviours. This will enhance research and impact practical work in the conservation domain for a sustainable future. A cross-cultural examination of the scale is still needed.

The planet is facing an anthropogenic mass extinction of wildlife, which will have a grave impact on the environment and humans. Widespread human action is needed to minimize the negative impact of humans on biodiversity and support the restoration of wildlife. In order to find effective ways to promote pro-nature conservation behaviours to the general population, there is a need to provide a list of behaviours which will have worthwhile ecological impact and are worth encouraging. In a novel collaboration between psychologists and ecologists, 70 experts from practical and academic conservation backgrounds were asked to review and rate 48 conservation related behaviours. According to their judgement, this short paper presents a ranked list of pro-nature conservation behaviours for the public in the UK and similar landscapes. This includes behaviours people can engage in in their homes, their gardens, on their land, and in their roles as citizens.
