UNED releases a free guide to help communities identify and monitor plant biodiversity

An open scientific resource for understanding local plant life

The National Distance Education University of Costa Rica (UNED) has made a free protocol available to the public to help identify, measure, and monitor plant biodiversity using simple methods supported by scientific standards. The initiative aims to make technical knowledge more accessible to students, teachers, local governments, environmental organizations, and anyone interested in learning about and protecting the plants in their surroundings.

The document, titled “Protocol for the Identification, Measurement and Monitoring of Plant Species at University Campuses,” can be downloaded free of charge from UNED’s official website. Although it was originally developed to strengthen environmental management across the university’s campuses, its methodology can also be applied in parks, schools, communities, and both public and private green spaces.

What does the protocol include?

The publication provides a standardized methodology for recording information about trees, shrubs, vines, and herbaceous plants in a consistent and comparable way over time.

Among the main tasks covered are:

Identifying plant species by their common and scientific names.
Correctly measuring tree diameter and height.
Evaluating the health condition of vegetation.
Assessing crown shape and sunlight exposure.
Detecting signs of deterioration, pests, or potential risks.
Recording observations to monitor changes in vegetation over time.

These practical tools enable anyone to collect valuable information for conservation projects, ecological restoration initiatives, or environmental monitoring programs.

Citizen science supporting conservation

One of the protocol’s main objectives is to promote citizen science, encouraging members of the public to participate in collecting scientific information.

According to UNED, providing an accessible methodology allows communities, schools, municipalities, and environmental organizations to collaborate in monitoring plant biodiversity while improving knowledge of local ecosystems.

This type of initiative strengthens environmental education and encourages greater public participation in protecting natural heritage.

A methodology based on scientific standards

Although designed to be easy to use, the protocol incorporates technical indicators commonly used in professional vegetation assessments.

These include:

Tree trunk diameter.
Tree height.
Crown condition.
Light exposure.
Plant health.
Presence of damage, fungi, or pests.

The information collected helps identify plants requiring monitoring, maintenance, or conservation measures before more serious problems develop.

A useful tool for communities and local governments

Beyond the university environment, the protocol can support urban tree inventories, ecological restoration projects, educational programs, and municipal environmental management plans.

Using standardized data collection methods makes it easier to compare information across different locations and generate reliable data for decisions related to green space conservation and land-use planning.

Why monitoring plant biodiversity matters

Plants form the foundation of nearly every terrestrial ecosystem. In addition to producing oxygen and storing carbon, they provide food, shelter, and habitat for thousands of animal, fungal, and microbial species.

Continuous vegetation monitoring helps detect changes caused by climate change, disease outbreaks, invasive species, or urban development, allowing faster responses to protect ecosystems.

In a country internationally recognized for its extraordinary biodiversity, providing accessible tools to document and understand plant life represents an important contribution to conservation and environmental education.

An open resource for learning and conservation

The publication of this protocol reflects UNED’s commitment to making scientific knowledge widely accessible while supporting the protection of Costa Rica’s natural heritage.

By offering a free, illustrated, and practical guide, the university encourages more people to participate in studying and monitoring plant biodiversity, helping generate valuable information for future generations.
