Digital tools are critical to the planning and management of suburban forests as they improve data collection, enable efficient resource allocation and enhance the visitor experience through better navigation and information dissemination. The aim of our work was to find out whether people visiting urban and suburban forests in Warsaw consciously plan their visits to forest areas, what ICT tools they use during and after a forest visit, and whether they share their experiences related to forest recreation on social media after the visit. The research focused on urban and suburban forests in the Warsaw metropolitan area, Poland. Data on visitors’ characteristics, recreation habits and digital skills were collected in an online panel survey in November 2023 (n = 1413). The results showed that respondents most frequently visited forest areas around Warsaw 2–3 times a month and several times a year. The vast majority of respondents planned their visits directly on the day of the trip (34.96 %) and used their own knowledge and experience when planning their trip to the forest. More than half of respondents (69 %) stated that they use various types of digital tools when visiting forest areas, most commonly smartphones with GPS functionality. Most respondents stated that they had advanced (43.38 %) or at least advanced (32.06 %) knowledge of using digital tools. 39.49 % of respondents stated that they do not use the internet to share information about their forest visits. The research results presented in the sentence indicate the complexity of using digital tools in the management of outdoor recreation and tourism. On the one hand, our research clearly shows that digital tools are an integral part of modern outdoor recreation and tourism management and provide valuable insights, on the other hand, most respondents planned their visits directly on the day of departure, relying mainly on their own knowledge and experience, rather than on digital tools. This knowledge can be used to develop forest management strategies, environmental education, monitoring tourist flows and promoting responsible recreation worldwide. Further research is needed to analyse the use of digital tools in digital forest recreation.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"18 ","pages":"Article 100697"},"PeriodicalIF":2.7,"publicationDate":"2024-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142433183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the several ways to mitigate CO₂ emissions is through afforestation, which prevents catastrophic environmental consequences. The mean average emission per tourist in the Canary Islands on their way to the islands is 0.48 Tn. Like most urban cities, the island of Gran Canaria faces the problem of CO₂ emissions due to anthropogenic and human activities. Vegetation coverage significantly influences the distribution of temperature. The correlation between Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) of Gran Canaria, using satellite images from Landsat 8 and Sentinel-2, revealed a strong inverse relationship within all land use types, with an R2 value of 0.39. Land suitability analysis is a prerequisite for optimum utilization of available land resources. This study developed a suitability map for afforestation based on land use land cover, topographic, meteorologic, and socio-economic factors. Eight factors, including distance from settlements, land use, distance from the road, distance from water, elevation, slope, precipitation, and temperature, were employed according to previous studies, expert consultation, and land suitability mapping experience. After the criteria decision and data acquisition, maps of each criterion were created and transformed using the Suitability Modeler of ArcGIS Pro. The current study results show that 87% of the total area is suitable for afforestation and reforestation projects in Gran Canaria. Instead of using reactive methods to lessen the effects, the study recommends a proactive approach to climate adaptation through nature-based solutions. The study is part of an umbrella project of the Canary Islands and Spain in general, which considers the contributions of local and institutional stakeholders at different stages of the project. The next stage will be to design a forest afforestation and reforestation project, considering the kind of tree species needed, the methods required to implement it, and the management guidelines about the initial years of installation and growth of the new trees. The most crucial technical choice is which forest species to choose, as it will determine the success of the reforestation effort. The new revegetated space's ability to sequester carbon dioxide will primarily rely on the productivity of the land used for forest reforestation, the species chosen, and the introduced planting density.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"18 ","pages":"Article 100698"},"PeriodicalIF":2.7,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142445448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using dendrochronological methods, we compared tree growth trends and responses to climate in tapped and non-tapped trees. Overall, tree growth was higher in resin tapped trees than in non-tapped trees, which were generally younger. However, tree growth decreased over time, increasing the negative effects of late spring temperatures, summer drought and reduced summer precipitation, with increased sensitivity to drought in tapped than non-tapped trees. Among tapped trees, those with larger wound area grew more than those less tapped, and were more sensitive to drought, particularly after the 80 s.

The paper explores the views of community-owned forest institutions to provide forest recreation. Sixteen cases have been studied in an alpine valley in Italy, where these institutions have been existing since hundreds of years. Q methodology was used. Q methodology is a semi-qualitative technique used to systematically analyze diverse points of view among individuals or groups by having them rank statements on a topic, allowing for the identification of similar views. Results show a general positive view of community-owned forest institutions towards providing recreation but with nuanced positions, which could be clustered in two groups. The first and largest group looked favourably at providing more forest recreation; the change towards forest recreation was however conditional to maintain adequate levels of income and receiving external support from public authorities. The latter and smaller group was more sceptical, being concerned about the potential negative impacts of visitors in the forest. Both groups stressed that sensitivity and respect of the visitors towards the property are decisive factors for accepting and improving public accessibility. The paper reflects on the challenges for these traditional forms of forest ownership in front of new societal demands, and concludes that, regarding forest recreation, the attitudes of community-owned forest institutions are not very different than those of other private forest owners.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"18 ","pages":"Article 100688"},"PeriodicalIF":2.7,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142421745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phosphite inhibits <em>Phytophthora</em> growth and sporulation whilst boosting defence responses in the plant host. It is unclear, however, the extent of the impact of phosphite on <em>Phytophthora</em> species assemblages and inoculum abundances in soil around trees following treatment within natural ecosystems. In New Zealand, kauri (<em>Agathis australis</em>), an endemic and threatened foundation species, suffers from a dieback disease primarily caused by <em>Phytophthora agathidicida</em>. Phosphite is applied by trunk injection to kauri and has been shown to improve resin ‘bleed’ symptoms from basal trunk lesions and to promote recovery of thinned canopies. <em>Phytophthora</em> community and inoculum abundance were investigated in response to phosphite treatments at two field sites (Huia and Waitoki) in infected kauri stands in Auckland, New Zealand. At Huia, soil sampling and tree health surveying were conducted in November 2023 on trees treated with phosphite in 2012 as part of an earlier study. At Waitoki, the response to phosphite treatment was monitored 6 and 18 months following treatment. <em>Phytophthora</em> species were detected using soil baiting and metabarcoding of Environmental DNA (eDNA) from soil and quantified with qPCR of root and soil DNA. Three species were detected with soil baiting (<em>P. agathidicida, P. cinnamomi,</em> and <em>P. multivora</em>) and two additional species with metabarcoding (<em>P. pseudocryptogea</em>, and an unknown clade 7 species similar to <em>P. europaea</em>). <em>Phytophthora cinnamomi</em> was the most abundant species, followed by <em>P. agathidicida.</em> Both species were more likely to occur together than by chance alone and were associated with declining tree health. The <em>P. europaea</em>-like species was in approximately 50 % of the samples and was less likely to occur in roots with poorer health, or in association with <em>P. agathidicida</em>. The abundance of <em>P. agathidicida</em> inoculum was lower in the soil around the phosphite-treated trees than around the untreated control trees 1.5 years after treatment at Waitoki. Phosphite halted the lateral expansion of basal resin bleeds, and resin viscosity was reduced. Not only did phosphite treatments improve kauri dieback symptoms, but the phosphite treatments potentially had a direct impact on the epidemiology of the disease by reducing inoculum load around treated trees, with direct implications for disease management as an effective way to protect uninfected areas and minimise the spread of inoculum from infested zones.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"18 ","pages":"Article 100687"},"PeriodicalIF":2.7,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142421744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
