“…More research is also needed to improve resistance to invasion by manipulating soil biota and species diversity (Brinkman, Raaijmakers, de Boer, & van der Putten, 2017; Callaway, Thelen, Rodriguez, & Holben, 2004; Funk, Cleland, Suding, & Zavaleta, 2008; Liao, Luo, Peng, & Callaway, 2015). Finally, there is a gap between scientific and practical knowledge in finding the best methods to control invasive plant species, and this gap can be reduced by providing awareness of what is exotic, involving local people in invasive species management (Dechoum, Giehl, Sühs, Silveira, & Ziller, 2019), and profiting from this activity (Shackleton, Le, Wilgen, & Richardson, 2017), such as when invasive trees are used as firewood or invasive grasses are used as fodder for domesticated animals.…”

Invasive plant species can hinder the establishment and growth of native plants and impact several ecosystem properties, such as soil cover, nutrient cycling, fire regimes and hydrology. Controlling invasive plants is then a necessary, yet usually expensive, step towards the restoration of an ecosystem. A synthesis of literature is needed to understand variation in invasive plants' impacts and their practical control in restoration contexts, and to identify associated knowledge gaps. We reviewed 372 articles published from 2000 to 2019 covering the control of undesirable plants (both exotic invasive and overabundant native plant species) in ecological restoration to gather information on the main plants being controlled and methods used, and considering the distribution of studies among biomes and countries grouped according to the Human Development Index (HDI). Grasses and forbs were the most‐studied invasive plant species in restoration sites, but invasive trees were well studied in the tropics. Poaceae and Asteraceae were the most studied families of invasive plants. Non‐chemical interventions (mostly mowing and prescribed fire) were used in more than half of the reviewed studies globally, but chemical methods (mainly glyphosate spraying, used in 40% of projects using herbicides) are also common. The reviewed studies were mostly performed in countries with very high HDI. Countries with low and medium HDI used only non‐chemical methods. Synthesis and applications. Decisions about which control method to use depend heavily on the invasive plant species' growth forms, the local economic situation where the restoration sites are located and resources available for control. More developed countries tend to use more chemical control, whereas less developed ones use mainly non‐chemical methods. Since most of the reviewed studies were performed in countries with very high HDI, we lack information from developing countries, which concentrates global hotspots for biodiversity conservation and global commitments of forest and landscape restoration.

“…The rate at which IAS spread and the difficulty of managing them, has resulted in the recognition of the need for collaborations in research and management that enhance the link between science, policy, management and citizens around the world (Novoa et al 2017;Abrahams et al 2019). These integrative management approaches Motivations and contributions of volunteer groups in the management of invasive alien plants in South Africa's Western Cape province should include citizens and volunteers to help improve the effectiveness of IAS management over the longterm (Novoa et al 2018;Dechoum et al 2019), and support conservation work in times of budgetary constraint (Pagès et al 2019).…”

“…According to Shackleton et al (2019), there are many ways of involving society in the management of IAS, such as through citizen science and volunteer initiatives to monitor and/or control IAS. Volunteers can make a significant contribution in the local management of IAS at a reasonable cost and their efforts can be sustained over time (Dechoum et al 2019). Volunteer programmes can also be helpful in increasing public awareness of environmental issues and encourage local people to join groups (Dechoum et al 2019).…”

Motivations and contributions of volunteer groups in the management of invasive alien plants in South Africa’s Western Cape province

Background: Research and management of biological invasions traditionally focuses on state operated large scale control initiatives, with little emphasis on volunteers. Volunteering can, however, contribute to detection, eradication and containment of invasive alien plant species (IAPS). Understanding the extent of involvement of volunteers in invasive alien species management is important. Similarly, understanding volunteers’ motivations to volunteering is important to improve the success of invasive alien species management. Objective: In this study we aimed to: 1) identify volunteer groups controlling IAPS in the Western Cape province of South Africa, 2) understand their practices and contributions towards detecting and controlling IAPS, 3) examine volunteer’s motivations for controlling IAPS, and, 4) identify the challenges individual volunteers and groups face. Methods: The data were collected using online questionnaires. Results: In total, we identified 52 volunteer groups. We broadly estimate that these groups clear nearly 8000 ha of land with estimated labour costs of ZAR 6.5 million annually (equivalent to USD 0.38 million) when aligned with formal state management cost estimates. Most volunteer groups raise their own funds to facilitate their work, however, many suggest support from government entities, landowners and Non-Government Organisations would help. Most volunteers (82%) detect and report invasive species to their team leaders, citizen science platforms and relevant authorities. Volunteers themselves gain physical and psychological fulfilment and build their social capital by meeting new people. Conclusion: Our findings point to the valuable contribution of these groups, but also the need for better co-ordination and engagement between volunteer groups and mandated authorities on science, policy and management.

“…In Brazil, the described invasions are mainly caused by the two most widespread species of the genus, P. taeda and P. elliottii (Ziller and Galvão 2002;Bechara et al 2013;Brewer et al 2018;Ramos et al 2019). An e cient control strategy has been eliminating adult pine trees that function as seed sources and not allowing the next generation to reach maturity ledding to changes in the population structure of pines in protected area (Dechoum et al 2019). However, other species must be studied in different environments to verify the potential for regeneration and implementation.…”

This study aims at determining the establishment potential of the main species of the Pinus genus planted in Brazil and broaden the knowledge on the conditions that facilitate the invasion. The density of regenerants neighboring pine stands planted with 35 populations of Pinus spp. (P. caribaea (var. bahamensis and var. caribaea), P. elliottii, P. kesiya, P. merkussi, P. oocarpa, P. patula, P. pseudstrobus, P. strobus, P. taeda, and P. tecunomanii) was evaluated in three locations in the state of São Paulo. The vegetal covers neighboring the pine stands were evaluated regarding native vegetation occupation, open area, and eucalypts plantation. The census of regenerants was conducted up to 100 m away from the pine stand edges; samples were collected over an area divided into four 25m-wide transects. In each transect, the regenerants were quantified and classified into three size classes: sprouts (≤ 0.3 m), seedlings (≥ 0.3 m ≤ 1.0 m), and trees (> 1.0 m). The results indicate that Pinus elliottii is the species with the greatest invasion potential in the studied areas since it adapts to different environments. Areas without established vegetation favored regeneration, indicating the effect of the environment on regeneration occurrence. The number of regenerants increased near the seed source but decreased significantly between 50 and 100 m away, despite the directional effect of the prevailing winds and the long-distance dispersal capacity of the genus.
