In Europe, forest fires are a serious and constant threat. They destroy forests and forest land, causing damage, financial loss, and long-lasting impacts on forest ecosystem services. There are several ways to decrease the number of forest fires, including continuous investment in fire prevention measures and the intensive implementation of adaptive sustainable forest management measures, which need additional financial resources. In many cases, forest management activities in karst forests are not implemented in a timely manner and in coordination with other stakeholders. A comprehensive study about the impact of forest fires on different economic activities (tourism and protected areas) is not currently available. In this study, the legislative framework in Croatia was analysed in relation to the fire protection activities and jurisdictions of different institutions. From data collected in the period 2013–2020, the first-age class afforestation costs and growing stock assortment value were calculated, and the non-wood forest functions were estimated. The aforementioned data were further compared to the Fire Weather Index (FWI) and Seasonal Severity Rating (SSR) of fire seasons. The total estimated damage is EUR 326,810,724.72. The research emphasises the need for the implementation of cross-sectoral forest policy measures. The state forest company should allocate more financial resources for biological forest restoration in the future. Forest management practices should implement climate-adaptable silviculture measures to preserve forest and forest land.

Forests in Croatia are characterized by higher levels of biodiversity in species composition. Three significant events occurred in Croatian forests over the past ten years, all of which have a common denominator—sanitary felling. The challenge in the sustainable development of forests started with the ice storm of 2014 that amounted to damage and raised costs in forest stands to EUR 231,180,921. The second challenge was in 2017 when the bark beetle outbreak occurred in the Gorski Kotar region. In December 2017, a windstorm in the same area caused damage to approximately 500,000 m³ of wood stock. The third climate extreme was in the summer of 2023 when three storms with strong winds and heavy rain damaged even-aged forests of common beech and pedunculated oak. The damage was substantial: 3,954,181 m³ of timber was mostly broken and destroyed across 21,888.61 ha of area, and the most damage was in the pedunculate oak forests of Slavonia, i.e., Quercus robur subsp. Slavonica, at 1,939,175 m³. For the main meteorological stations in lowland Croatia, data on precipitation amounts (mm) and wind speeds (m/s) were collected for the period 1981–2023, and the results of our analysis for the last decade are presented. Meteorological drought was analyzed using the rain anomaly index RAI. Data regarding open space fires in the Mediterranean karst area of Croatia were collected from the Croatian Firefighting Association, and the calculation of the burned area index (BAI) was determined. Throughout the entire area of Gorski Kotar County, a sample of permanent plots was set and used to assess the extent of forest damage from the ice storm in 2014 and for the establishment of permanent monitoring of the recovery of trees and forests damaged by the ice storm. The monitoring of bark beetles in the Gorski Kotar region started in 1995 and is still in progress. The aftermath of bark beetle outbreaks in two uneven-aged silver fir stands was studied after a bark beetle outbreak and a sanitary felling of 4655.34 m³. In the area of lowland Croatia, a statistically significant and positive correlation was found between sanitary fellings, maximum wind speeds, and rain anomaly indices in even-aged forests. In conclusion, sustainable development will be at risk due to difficult recovery, rising costs, and overall climate change in the years to come.

Climate conditions have long been recognised as an important factor influencing the start and spread of forest fires in Mediterranean areas. This is partly due to the long dry periods that characterise these regions. Mixed forest ecosystems are more stable than monocultures. This study was conducted at two sites, the city of Makarska (the southern coast of the Croatian Mediterranean) and the island of Rab (the northern island of the Croatian Mediterranean). The main variables examined, flammability, combustion and the moisture content of potential forest fuel, best define the start and spread of fires. The aim of the study was to examine the influence of climate factors on these variables using the example of mock privet (Phillyrea latifolia L.). The results showed that moisture content of fuel was a key variable in direct correlation with the influence of climate factors. Though the Mediterranean region is burdened by fires and they will continue to occur in the future due to changing conditions, the study results can contribute to reducing burned areas in fires for the purpose of preserving Mediterranean ecosystems.

Urbanisation is a common cause of the loss of biological diversity. The most diverse natural areas in urban centres are city parks. The aim of this study was to examine the importance of songbirds for park visitors, the environment, and biodiversity in cities, based on the example of the Croatian coastal belt. A survey was conducted in the first half of 2024 (survey N = 662). The results show a low degree of basic biological knowledge of the main songbird species present in urban parks along the Croatian coastal belt. Citizens, on average, had a good basic understanding of the relationships between park songbirds and the environment. There were no statistically significant differences between cities of residence concerning basic biological knowledge of the main park songbird species in the Croatian coastal belt (p = 0.076), basic knowledge of the relationships between park songbirds and the environment (p = 0492), interactions between humans and songbirds in parks (p = 0.403), or opinions on conserving park songbird populations (p = 0.115). The final analysis confirmed that there was a statistically significant difference in education levels among participants regarding basic biological knowledge of the main park songbird species in the Croatian coastal belt (p = 0.001), basic knowledge of the relationships between park songbirds and the environment (p = 0.014), interactions between humans and songbirds in parks (p = 0.001), and opinions on conserving park songbird populations (p = 0.041). The dominant role of female respondents also raises the question of why male respondents do not participate in the research, which opens up opportunities for new research that would mainly deal with the topic of gender differences in attitudes towards park birds.

U radu su analizirane mjere potrebne za protupožarnu zaštitu i s njima povezani troškovi koji se odnose na razdoblje prije, za vrijeme i poslije požara. Razvidno je da se troškovi povećaju u uvjetima učestalih požara. Stoga je nužno intenzivirati preventivne mjere i radove koji mogu smanjiti rizik od nastanka požara otvorenog prostora i utjecati na smanjenje površine zahvaćene požarom. U radu su navedene preventivne mjere koje bi se trebale provesti svake požarne sezone radi učinkovitosti sustava protupožarnih aktivnosti. Naime, njihova učinkovitost izravno može utjecati na smanjenje ukupnih troškova prilikom gašenja požara jer je potrebna manja potrošnja i korištenje resursa u vatrogastvu. Troškovi su visoki kada se uzima u obzir vatrogasna intervencija zemaljskih snaga koja se povećava sudjelovanjem protupožarnih zrakoplova. Ključno razdoblje u kojem preventivne mjere trebaju biti uspješno provedene je tijekom požarne sezone od 1. lipnja do 30. rujna. Također, svako ulaganje u preventivne mjere u šumarstvu smanjuje troškove sanacije požarišta te obnove šuma i šumskih zemljišta.
