Room to regenerate: microhabitats and the recruitment niche as drivers of mountain woodland restoration

Restoration Ecology, EarlyView.
Abstract Introduction Natural regeneration is an efficient, minimal‐intervention approach essential for facilitating resilient, self‐sustaining ecosystems during woodland restoration. However, recruitment can be slow, uncertain, or highly restricted, particularly in mountain woodland systems where tree planting and large herbivore management are ...

Hybrid barrier systems for rockfall protection [PDF]

, 2008
This study examines hybrid barrier systems, incorporating field performance, limited rockrolling tests, and finite-element modeling. A hybrid barrier is a passive rockfall protection system consisting of a flexible fabric suspended from a top horizontal ...

A nonlinear model coupling rockfall and rainfall intensity based ewline on a four year measurement in a high Alpine rock wall (Reintal, German Alps) [PDF]

Natural Hazards and Earth System Sciences, 2009
A total of more than 140 000 kg of small-magnitude rockfall deposits was measured in eight rockfall collectors of altogether 940 m² in size between 1999–2003 below a 400–600 m high rock face in the Reintal, German Alps ...

Significance of substrate soil moisture content for rockfall hazard assessment [PDF]

Natural Hazards and Earth System Sciences, 2019
Rockfall modelling is an important tool for hazard analysis in steep terrain. Calibrating terrain parameters ensures that the model results more accurately represent the site-specific hazard. Parameterizing rockfall models is challenging because rockfall

Resolving a debate over social freedom

The Southern Journal of Philosophy, EarlyView.
Abstract When I am unable to drive due to a road blockade, there seems to be a morally relevant difference between a case in which the road is blocked by workers and a case in which the road is blocked by a landslide. Many political philosophers tried to capture this pretheoretical judgment at a more abstract level through the formulation of a concept ...

3D Analysis of a Fragmental Rockfall

, 2020
Fragmentation in a rockfall event influence the total number of fragments, the mass distribution, and the impact energies and runouts. Then, the probability of impact and hazard characterization should consider fragmentation. A fractal fragmentation model has been proposed in order to reproduce the phenomenon.

Application of image quality assessment for rockfall investigation [PDF]

, 2019
This paper presents an automatic image sensing method to detect rockfall events using time-lapse photographs and digital image processing. Based on the change detection concept, an image quality assessment procedure is proposed to detect rockfall events ...

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Seismic Insights Into the Role of Rockfall in Rockslide Destruction Processes

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The dynamic link between rockslide failure and rockfall activity remains elusive, primarily due to the challenge of detecting weak signals amidst high noise. We propose a seismic attribute guided deep learning framework that formulates rockfall detection as a time‐series segmentation task, facilitating the precise extraction of rockfall events
