As well as providing useful information about the surrounding natural area (e.g. trails, routes) and relevant information about this (e.g. routes’ terrain, length, degree of difficulty, changes in altitude), the trail centres also educate users on how to behave in nature. Codes of conduct educate users about how to respect nature while enjoying their sport/activity in a natural environment. For example, centres may provide information about how to respect nature when walking, running, or cycling on the local tracks, trails, and routes.

Some centres also provide information about the natural and cultural history on the routes, increasing users’ awareness of their natural environment.

The Trail Centres act as physical spaces that increase and improve access to physical activities in nature, contributing to physical and mental well-being.

Their carefully chosen locations in proximity to nature (forests, water, and trails) help establish freely accessible, round-the-clock meeting places and start-points for outdoor sporting activities. As some are located close to urban areas, they also provide a gateway from urban to natural environments. 

Their combination as an all-in-one clubhouse, provider of service facilities, and meeting and training space, makes them ideal sites for local sports associations to use, as well as un-affiliated groups or individuals. This provides a space for socialising within, and between, sports and promotes relationship-building amongst users and with local sports associations.

Providing access to service facilities participation in outdoor sports activities (e.g. bicycle pumps and cleaning stations; covered training space; functional training equipment (stairs, monkey bars, TRX, etc.); storage space for equipment; and changing rooms/showers/toilets). As sites for borrowing equipment (e.g. map and compass, roller skis, SUP boards, etc.), the centres also encourage people to try new activities in nature in an affordable manner. 

The trail centre project was built on cross-sectorial cooperation. The five trail centres that are being built have all been developed and built in close collaboration with stakeholders across different sectors. These included the local municipalities where the centres would be built, the local sports associations who would be using the sites, local citizens and would-be users, as well as other interested parties. 

The participatory approach included holding 4 to 5 workshops with stakeholders to understand user needs, ideas, etc. This both enabled and ensured dialogue between the architects involved in the planning and design processes of the trail centres and the users/interested parties. Dialogue with architects also ensured that the buildings’ aesthetics, as well as functions, met stakeholders’ wishes.

The activities provided, or facilitated, by the trail centres were developed in collaboration with the local actors and associations. A participatory approach to planning also gives the users and local community a greater sense of ownership and helps ensure a sense of community between actors and across their respective sports.

Additionally, the development of the minimum criteria for determining the location and functions of the trail centres arose through cross-sectorial collaboration between project members.

To ensure the success of trail centres, the project members developed a number of minimum criteria for the location and design of the trail centres. Criteria was also established regarding the minimum service functions that the trail centres need to accommodate as well as the information that centres need to present. 

Minimum criteria:

• located at the centre of a varied range of trails, routes, and tracks that are preferably marked
• situated in an interesting park area, terrain, landscape or natural area
• information about e.g. the routes’ terrain, length, degree of difficulty, changes in altitude
• parking spaces
• a common room that all sports associations can use
• a covered area for e.g. gatherings, warm-up stretches, abdominal exercises
• a good range of relevant service functions

Each of the centres that have been, or are being, developed adhere to these minimum criteria. They are all located in or near natural environments that provide access to different outdoor sporting activities. Core service functions are integral to the architectural designs of each centre. 

Drones play a pivotal role in the 3LD-Monitoring system, complementing other data collection methods.Drones are essential tools in partner countries to fortify technical skills among local staff. These skills encompass flight planning, navigation and image evaluation. The drone monitoring aims to empower project staff to capture data tailored for photogrammetric analyses, from which crucial geoinformation emerges.

The drone mapping methodology encompasses five stages, with the first two focusing on drone operations:

1. Mapping mission preparation (desktop work)
2. Mapping mission execution (fieldwork)
3. Development of Digital Surface Model (DSM) & Orthomosaic generation (desktop work)
4. Data analysis and refinement (desktop work)
5. Integration into the prevailing data system (desktop work)

Drone data aids in evaluating indicators linked to carbon/biomass, such as mortality rates and forest types. Notably, with the application of allometric equations and proper characterization of the land type, above-ground biomass estimations of trees can be determined.

Satellite data forms the bedrock of the 3LD-Monitoring system, harnessing the capabilities of open-source imagery from the Copernicus Sentinel-2 and LANDSAT satellites. An algorithm, meticulously developed by Remote Sensing Solutions (RSS) GmbH, revolutionizes this process. Users can seamlessly submit the shapefile of their area of interest, prompting the algorithm to automatically fetch and analyze relevant data. A spectrum of robust analyses are conducted including the 5-year vegetation trend using NDVI for assessing vegetation gains or losses, 5-year vegetation moisture analysis through NDWI, and a nuanced 5-year rainfall trend evaluation. Additionally, the algorithm facilitates the visualization of vegetation changes since the inception of the project, bolstering the monitoring framework with dynamic insights. Satellite data, a vital component of the 3LDM-Monitoring system, leverages open-source imagery from the Copernicus Sentinel-2 mission and LANDSAT satellites. For predefined areas, this data is automatically fetched and analyzed for specific parameters. Key analyses include a 5-year vegetation trend using NDVI as a proxy for vegetation gains or losses, a 5-year vegetation moisture trend through NDWI, and a 5-year rainfall trend. In addition vegetation changes from project start can be visualized.

Satellite and drone images, despite their undeniable contribution for monitoring, they are limited in the initial years of FLR efforts. Data collection at field level is crucial in the first projects years.

Data collection at field level is further divided into three participative approaches:

• Permanent sampling plots: Fixed plots, where tree height, DBH, and tree survival rates will be estimated. Permanent sampling plots will be assessed in 3-year interval, due to their high labor and time input.
• Land use planning: discussion rounds for the assessment of information, as well as identification of endangered species according to the Red List of Threatened Species by the World Conservation Union (IUCN). It is integrated into other land use planning processes, and thus, has not a defined assessment interval.
• Transects: Identification of floristic and faunistic species, as well as forest structure composition, in an assessment interval of three months

All relevant indicators included in the three participative approaches are collected using the KOBO Toolbox. This software offers suitable conditions and is easy to operate, aligning with the monitoring objectives of the project.
