It is increasingly possible to harness publicly available data posted by park visitors to fitness platforms and combine it with other spatial and field data to help prioritise management actions and enhance conservation and visitor experiences. Here we outline and then apply such a desktop methodology to assess the extensive network of formal and informal mountain biking trails in a popular urban national park in Australia. Across Nerang National Park on the Gold Coast, 31.4 km of formal and 36.2 km of informal mountain bike trails were identified and assessed using data from the popular fitness platform Trailforks and existing trail records from managers. Informal mountain biking trails were mostly in the higher and more remote parts of the Park on steeper slopes and were generally less popular than the formal trails closer to the main entrance. The informal trails have resulted in the loss of 0.8% of vegetation, increased fragmentation and potentially disturb wildlife across 13% of the Park, with some informal trails traversing an important wetland catchment. The results demonstrate the scale and nature of potential impacts of informal trails, which have doubled the area of trails in Nerang National Park. They highlight the need for specific management actions, such as closing and restoring informal trails, particularly when poorly designed and in areas of high conservation value.</p>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"26 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/emr.70011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The decline of TEK in the Pacific and Papua New Guinea (PNG) has highlighted the need to examine how modern faiths, like Christianity, which is the most prevalent in the Pacific, might aid or impact conservation that was previously guided by TEK. Along the Kokoda Track in Central Province, PNG, we assessed the impact of the Seventh-day Adventist church on the Indigenous Koiari People and their knowledge of the endemic Vanate (Raggiana Bird of Paradise, <i>Paradisaea raggiana</i>), which is PNG's national emblem. Two focus group discussions (four and five respondents respectively) and 39 in-depth interviews were conducted with Indigenous Koiari People. We collected information regarding the impact of Adventism on TEK, Vanate conservation and the environment in general. We assessed six adult age cohorts across four villages (including representatives of 17 Tribes/clans) of men and women along the Kokoda Track. Most respondents, especially men, claimed that Adventism had caused a decline in TEK and values and altered conservation practices and diet. We found that Adventist faith encouraged the Indigenous Koiari People to protect the Vanate and its environment by not eating it; however, this was at the expense of TEK, traditional conservation practices and language. However, Koiari People were found to still hunt the Vanate, largely to generate income from their feathers, which were still used in cultural dancing and important for tourism. This research is useful for conservation decision-making and practice as it highlighted the changing motivations underlying conservation, gendered responses and identifies ways for scientists and policymakers to collaborate, accept and incorporate Indigenous People, their religious beliefs and practices for conservation of birds like the Vanate.</p>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"26 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/emr.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For stored baits, there was no effect of time on recovered 1080 for up to 2 months (maximum length of study), indicating different storage methods were equally effective in maintaining lethal baits. Manufactured sausage baits contained significantly more 1080 than DMB manufactured for this study, and showed substantial variability in recovered 1080 dose, which could reflect gun handling error. Storage in a locked transport box resulted in marked insect damage, likely rendering baits unattractive to target species. Freezing baits did not result in reduced 1080 dose. The majority (93%) of deployed/stored baits had a lethal 1080 dose recovered (13/192 baits were below the LD₅₀ for a 20 kg dingo).

This barrier to restoration has stimulated a number of methods to help combat this issue, including the burial of seeds just below the soil surface, the addition of fertiliser and the use of other suitable low-cost soil amendments aimed at improving germination and survival. This study examines the effects of burial depth and application of soil amendments on seedling emergence under different watering regimes on four semi-arid zone species. The soil amendments used were hydrogel (EarthCare Water Crystals), fertiliser (Osmocote), and a commercial soil microbial inoculant (Bactivate5). It was found that, while heavier seeded species were able to emerge from deeper below the soil surface, all seeds in the study preferred to emerge from shallow burial depths of around 6–10 mm. Soil amendments were shown to have minimal effect on emergence rates, regardless of the watering regime, while the watering regime was found to have the largest impact. Seedlings under a low watering regime (30% water holding capacity) were found to have the lowest emergence rate, while a moderate watering regime (55% water holding capacity) produced the highest emergence across most species. Results obtained from this study suggest that shallow burial of seeds 6–10 mm below the soil surface, as opposed to surface placement or deeper burial, may enhance emergence for the species tested. Although the soil amendments did not improve plant species emergence, amendment application may still be beneficial for developing seedlings by enhancing seedling resilience to adverse growing conditions such as moisture stress or extreme temperatures.</p>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"26 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/emr.70010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quality of these habitats directly influences migration success, particularly for small passerine birds that depend on readily available food resources. However, high-quality habitats are often scarce at stopover sites. In the Republic of Korea, the Biodiversity Management Contract Scheme (BMCS) aims to enhance habitat quality by providing food resources through unharvested cultivated land (UCL). This study evaluated the effectiveness of BMCS on Heuksando Island, a major stopover site for migratory birds. We compared the number of species and individuals and habitat usage time of migratory birds in UCLs and control deserted lands (DLs). The results showed higher species richness and abundance in UCLs than in DLs, with buntings (family Emberizidae) being particularly numerous in UCLs. Additionally, habitat usage times were significantly longer in UCLs. While BMCS provides critical food and shelter for granivorous birds like buntings, the potential impacts on non-target species warrant further investigation. These findings showed the importance of BMCS in enhancing high-quality habitats for small migratory birds to feed and hide in, while also suggesting the need for a balanced approach to ensure broader biodiversity conservation.</p>\u0000 </div>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"26 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twelve different CMT types are described, representing a variety of historical themes including the paddle steamer shipping industry, forestry, local land settlement and water resource management. Threats to the trees, in addition to their inevitable ageing and death, include fire, flood, river regulation, vandalism, road maintenance work, boundary clearing and illegal felling for firewood. This study provides an example of the diversity of historic heritage trees to be found in Australian conservation reserves and highlights how these trees can contribute to the appreciation of these reserves as historical cultural landscapes.

Arundo grows more with nitrogen (N) amendments and can outcompete native woody species in high-N conditions characteristic of intensive agricultural runoff, but its competitive dynamics at N levels characteristic of less intensive agriculture have not been assessed. Restoration efforts typically do not consider minimising conditions that make ‘invaders’ so successful in a given area, such as the range of upland N inputs; however, such distinctions may be important in identifying areas with higher chances of successful native plant restoration. Here, we addressed how different levels of N addition influenced competition between Arundo and a dominant native California woody species, <i>Salix lasiolepis</i> (Arroyo Willow), by simulating a post-flooding scenario: Arundo rhizomes are deposited and establish within Arroyo Willow stands and receive nitrate (NO₃⁻) from agricultural runoff. We added Arundo rhizomes to established Arroyo Willows in individual pots of riparian soil (in the greenhouse), and added NO₃⁻ weekly for 4 months at the following levels: no addition, low (24 g/m² year.⁻¹ N), or high (120 g/m² year.⁻¹ N). Arundo inhibited Arroyo Willow growth by 57% in high-N conditions, but did not inhibit Arroyo Willow in low- or no-N treatments. Across all treatments, Arundo had greater leaf N%, higher potential photosynthetic N use efficiency, but produced less root biomass than Arroyo Willow, suggesting that it dominated access to NO₃⁻ without needing to invest in root infrastructure. Arundo had similar net assimilation of CO₂ (A_net) as Arroyo Willow, but greater leaf biomass, increasing its photosynthetic potential. These findings suggest that upstream agricultural NO₃⁻ management can either enhance or constrain Arundo success. Plant restoration practices should prioritise whole watershed management of Arundo removal areas, integrating consideration of upstream N dynamics and runoff so as to limit NO₃⁻ inputs.</p>\u0000 </div>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"26 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our goal was to evaluate a method of vegetative propagation of xaxim (<i>Dicksonia sellowiana</i>), an endangered tree fern from the Atlantic Forest, under different light conditions. We conducted two experiments on an experimental farm in the Araucaria Forest domain. One experiment was installed under an Atlantic Forest canopy (shade), and the other was installed in an open area surrounded by a forest with direct sunlight (without shade). All individual plants were standardised in height and frond number by removing all fronds and removing lower trunk material where trunks were longer than 50 cm. We tested three different propagule treatments: whole propagule (1 propagule), propagules cut in half lengthwise (½ propagule) and propagules cut into four equal parts lengthwise (¼ propagule). Each experiment was conducted in a randomised complete block design with four replicates. We evaluated survival, total height and diameter at ground level 6 and 10 years after the implantation, as well as the increment in those years. For survival data, the interaction between shade condition and propagule manipulation method was nonsignificant (<i>p</i> = 0.256) (joint analysis of experiments), and survival rate was higher for shaded propagules (58%) when compared with propagules exposed to light (41%). Higher survival was also observed for whole plants (96%). The mean height obtained from the shade experiment was statistically different among the different propagule sizes in both measurements and in the increment. The use of whole plants for transplanting of xaxim propagules significantly increased their chances of development. We recommend the establishment of whole propagules in shaded environments to ensure greater efficiency in the transplant process of this species of tree fern.
