Fog and Nature

Ecological Research

My academic route started in urban ecology, and shortly after coming to Oxford's Ecosystem Lab I fell in love with tropical ecosystems occurring right on the upper reaches of our most spectacular mountain ranges.

Restoration of high altitude forests in the Peruvian Andes


Socio-ecological research on the barriers and success factors for restoration of mountain forests in the High Andes. For this research I work with multiple NGOs, government actors and communities and use interviews to elucidate on how to best restore these threatened ecosystems.

Satellite data for monitoring of forest recovery in the Andes


Remote sensing analysis of forest recovery following disturbance in tropical montane forests of South America through a combination of multi-spectral and multi-temporal data analysis methods.

Young voices in restoration science


Increasing representation of early career scientists in the discourse of ecological restoration through providing a forum at conferences and with a special feature in the journal Restoration Ecology.

Ecological restoration in tropical mountains


Synthesis of knowledge on mountain restoration across the various mountain ecosystems and across restoration methods and disturbance contexts.

Functional ecology in the mountains of the Brazilian Atlantic Forest


Study of the functional assembly and stress-tolerance of trees growing in tree islands amidst grasslands above the tree line. What traits, strategies and trade-offs do they exhibit and what does it mean for their response to climate change?

Grassland phenology & urbanisation


Study on how the life cycles of herbs and grasses growing in cities respond to the city climate and urban structures.

Useful resources

Open access data & science are my 21st century love story!
Below I share information on great data portals and tools for ecology & conservation!

Restor - an innovative platform to catalyze action in the global restoration movement

A science-based open data portal where restoration practitioners can enter & exchange data on their restoration projects and connect with each other.

Provides satellite-data based information on forest restoration potential and success!

Mountain ecology

Mountains are hotspots of biodiversity and provide numerous ecosystem services to people across the world.
Check out the mountain portal from the Global Mountain Biodiversity Assessment which collates knowledge on mountain ecology!

Google Earth Engine

A planetary-scale data portal and processing engine containing all sorts of satellite imagery, climate models and land use data.

Download, process and model large-scale satellite data using the earth engine JAVA language. All powered by google's cloud service. A number one tool for environmental research these days.

Aerial View of Deforestation

Monitoring deforestation & forest recovery

Deforestation is one of the most harmful processes of global change, resulting in biodiversity loss, desertification and exacerbating climate change. tracks deforestation across the world by using satellite data in a very clever way! They also provide data on biodiversity and climate - all satellite and big data-base derived!

Functional ecotypes

Biodiversity is not only the diversity of species, but also the multitude of functions and processes in ecosystems. This functional perspective is key to understand how species will respond to climate and global change and to design meaningful conservation interventions!

Check out this magnificent resource by the IUCN providing a categorisation of the Earth's ecosystem types and functional groups.

Kew Garden Reforestation Conference

I attended the 2020 Kew gardens Reforestation for Biodiversity, Carbon Storage & Livelihoods conference. 
Check out my visual summaries below on the key messages from three productive conference days!
