Fire is one of the main disturbances of the forest ecosystems, impacting on forests structure such as flora and fauna composition, soil nutrient status and understory plant biomass. This study aimed to present the preliminary results of the monitoring of vascular plant composition, species richness, density (individuals/m2), cover (%) and biomass (g m−2) in three burnt and restored forest areas in Greece (located in Attica, Peloponnese and Western Greece, in the framework of the project MoRe Forest: “MOnitoring the impact of REstoration works in the post fire forest environment in Greece”), one year after the wildfire and after the construction of different types of restoration works. The plant species density and cover were determined through sampling of 1m2 plots. In the study areas of Attica, Peloponnese and Western Greece, 21, 23 and 45 plant species were identified, representing 13, 12 and 20 families, respectively. From the floristic analysis, it was found that the richest families, in terms of number of species, are those of Poaceae, Asteraceae, Fabaceae, followed by Cistaceae. Significant statistical differences (F = 2.46 and p = 0.03) were detected in the plant density among the different types of interventions (log-barriers, log-dams and wattles) and at the zones defined in the area between two consecutive restoration work units (eroded and deposition zones). More specifically, the plant density of all detected species varied from 2.88 ± 4.91 at the log-dams-deposition zones to 23.11 ± 4.81 at the log-barriers-eroded zones. In addition, plant cover was at satisfactory levels (max: 50%) at all interventions types and zones. The plant biomass dry weight per m2, presented a high difference (about 40 g m−2) between the log-barriers deposition (82.53 g m−2) and eroded zones (42.55 g m−2), whereas at the other interventions (log-dams and wattles) no significant differences between the eroded and deposition zones were detected. Overall, this work contributes to the enhancement of knowledge about the evolution of plant composition and plant diversity in degraded by fire forest ecosystems after restoration.

摘要

Fire is one of the main disturbances of the forest ecosystems, impacting on forests structure such as flora and fauna composition, soil nutrient status and understory plant biomass. This study aimed to present the preliminary results of the monitoring of vascular plant composition, species richness, density (individuals/m2), cover (%) and biomass (g m−2) in three burnt and restored forest areas in Greece (located in Attica, Peloponnese and Western Greece, in the framework of the project MoRe Forest: “MOnitoring the impact of REstoration works in the post fire forest environment in Greece”), one year after the wildfire and after the construction of different types of restoration works. The plant species density and cover were determined through sampling of 1m2 plots. In the study areas of Attica, Peloponnese and Western Greece, 21, 23 and 45 plant species were identified, representing 13, 12 and 20 families, respectively. From the floristic analysis, it was found that the richest families, in terms of number of species, are those of Poaceae, Asteraceae, Fabaceae, followed by Cistaceae. Significant statistical differences (F = 2.46 and p = 0.03) were detected in the plant density among the different types of interventions (log-barriers, log-dams and wattles) and at the zones defined in the area between two consecutive restoration work units (eroded and deposition zones). More specifically, the plant density of all detected species varied from 2.88 ± 4.91 at the log-dams-deposition zones to 23.11 ± 4.81 at the log-barriers-eroded zones. In addition, plant cover was at satisfactory levels (max: 50%) at all interventions types and zones. The plant biomass dry weight per m2, presented a high difference (about 40 g m−2) between the log-barriers deposition (82.53 g m−2) and eroded zones (42.55 g m−2), whereas at the other interventions (log-dams and wattles) no significant differences between the eroded and deposition zones were detected. Overall, this work contributes to the enhancement of knowledge about the evolution of plant composition and plant diversity in degraded by fire forest ecosystems after restoration.
