In order to find the best and most reliable practices for ecological restoration of degraded lands, longer time scales should be considered when evaluating restoration efforts. We assessed the long-term (16 years) effects of different grassland restoration treatments-seeding, mowing, and carbon amendment-in the Pannonian sand grasslands. After re-p...

The lack of knowledge on the traits related to the germination and establishment of native plant species represents obstacles to restoration. Seed mass, germination and emergence variability from two characteristic grasses ( Festuca vaginata and Stipa borysthenica ), and two dicots ( Centaurea arenaria and Dianthus serotinus ) of Hungarian sandy gr...

To help upscale ecological restoration of degraded lands, landscape factors and longer time scales should be considered when assessing restoration efforts. We evaluated the impact of initial restoration intervention, landscape composition, and elapsed time since the restoration began on the long-term progress of Pannonic sand grassland restoration....

Even though plants represent an essential part of our lives offering exploitational, supporting and cultural services, we know very little about the biology of the rarest and most threatened plant species, and even less about their conservation status. Rapid changes in the environment and climate, today more pronounced than ever, affect their fitne...

Aim There is increasing recognition that plant‐soil feedbacks drive species coexistence, therefore the belowground compartment should be better considered in ecological restoration. Addition of carbon is a restoration measure that relies on indirect plant‐soil relationships by soil nitrogen immobilization in microbial biomass to manipulate competit...

Urban-industrial restoration of complex native vegetation, such as grassland-forest mosaics could counteract land degradation and help develop methodology for larger scale complex restorations. We have studied the impact of grassland reconstruction techniques, the resulting biotic conditions, plus abiotic conditions on early woody survival in a for...

There is limited availability of seeds of native species in many countries for grassland restoration therefore ex situ seed banks can gain importance as source of germplasm in the future. We tested the usability of seed accessions of the Pannon Seed Bank for reintroduction with the aim to restore sandy grassland in Hungary. Seeds of ten native sand...

Invasive species are among the main threats to grassland biodiversity, and nature conservation management seeks the best methods to eliminate them and to restore natural habitats. We studied the long‐term effect of mowing on the restoration of Pannonian sand grassland after elimination of invasive black locust (Robinia pseudo‐acacia) plantation in...

To preserve the natural genetic pattern of species and to avoid the introduction of non-adapted ecotypes during restoration, seed transfer should be spatially restricted. Instead of applying administrative borders in the absence of species-specific empirical data, biogeographical knowledge can be used as a proxy. Hungary was used as a suitable test...

A kaszálás hosszú távú hatását vizsgáltuk nyílt homoki gyepek regenerációjára akác-állományok felszámolását követően. Három homoki akácállomány került letermelésre 1994/1995 telén. Az akáctönköket vegyszeres lekenéssel kezeltük, majd a terület egy részén évi kétszeri kaszálást alkalmaztunk 1995 és 2001 között. A vegyszeres kezelés sikeresen visszas...

Aichi Target 15 aims to enhance the resilience of ecosystems through the restoration of 15% of degraded land by 2020. Compliance with the target is still insufficient, partly due to the lack of appropriate baselines and knowledge of restoration efforts. The four-level model of ecosystem condition was suggested to set the baseline and support the es...

Questions The restoration of unused urban‐industrial areas has largely been neglected despite their great potential for nature conservation purposes. We applied three plant introduction treatments at a highly degraded industrial area to test whether plant material introduced to industrial areas initiate plant assemblages similar to the composition...

Scaling-up ecological restoration demands the involvement of private sector actors. Experience regarding science-based habitat restoration programs in the sector should be made available to support further joint projects. In our case, hierarchical restoration prioritization was applied to select best target for habitat reconstruction at a Hungarian...

There is a lack of knowledge on germination capabilities of native species and their relation to field establishment that could help optimize ecological restoration efforts. We studied laboratory germination and second year field establishment of 12 native vascular dry grassland plant species in the frame of a restoration project in NE Hungary. Our...

Species richness, composition and abundance of the bryophyte diaspore bank of Central European temperate mixed forests were compared with the forest-floor bryophyte assemblage. The impact of environmental variables and anthropogenic disturbances, including tree species composition, stand structure, microclimate, light conditions, soil and litter pr...
