We aim for as much diversity as possible on Milagros.
We aim for as much native plant diversity of Milagros as possible, and as much diversity – native and non-native – as possible in the food forest near the houses. With plant diversity, we hope to encourage habitat and food for a greater diversity of wildlife.
There is another form of diversity that’s as important, and that’s the diversity of ecosystems.
DIVERSITY OF ECOSYSTEMS
We already have a diversity of ecosystems here. In the area of the big pond, we have a relatively mature forest with tall trees. We have a semi-riparian (?) zone where the creek (small river) goes, although this seems only to have water when it rains. (From what neighbors say, it used to flow year-round.) We have grassland with some trees of different sizes. (Used for grazing.) We have many areas of brushland with some trees, pioneer species, and more. We have dense young forests with pioneer species. We have a growing food forest with native bushes and trees mixed in.
WHAT WE WILL DO
As we support the ecosystems here to be more diverse, healthy, and vibrant, we want to keep this in mind.
Some of this seems relatively straightforward – we want to support the riparian zone, we want to support reforestation in many areas, and we will continue with the food forest near the houses.
I am not so sure about the savannah or grassland. Maintaining that will require grazing animals, and we may include that in some zones in the future. In any case, the neighbors have plenty of grassland and savannah since they graze cows.
What about the brushland? This will naturally evolve into a forest given time and opportunity. Should we try to maintain some areas as brushland?
We will continue to prune in the food forest to provide mulch and nutrients for the soil and to open it up for air and sunlight. We may also prune some in the wilderness areas, although only if specialists recommend it and under their guidance.
All of this will depend on learning more, what specialists recommend, how many resources we have, and how it all evolves in general.
THE DIVERSITY OF EDGES
Each of these ecosystems will tend to have and attract unique species, and there is something special that happens at the edges: They have species from the two ecosystems and also some that especially thrive at the edge.
That’s another reason for having a diversity of ecosystems: It creates more edges and invites even more diversity at those edges.
THE IMPORTANCE OF DIVERSITY
Why do we want as much diversity as possible?
The short answer is that healthy ecosystems are wildly diverse. In most cases, you cannot have one without the other.
Diversity creates healthy soil, and healthy soil supports diversity. Diversity allows some to thrive where others do less well. Diversity ensures all the nooks and crannies are filled in. Diversity allows the system as a whole to better adapt to changing conditions. (Including changing climate.) Diversity of plants supports a diversity of wildlife. Diversity of plants, wildlife, and ecosystems prevents one species from taking over and becoming a problem. Diversity produces a wide range of food for wildlife and us.
It offers far more opportunities for income: Fruits, berries, seeds, saplings, education, workshops, eco-tourism, mulch, compost, and so on.
We evolved with diversity. It helps us come alive. For us, diversity in nature is fun, exciting, fascinating, and beautiful. (Not for all of us, which I suspect has to do with disconnect and possibly trauma, and that disconnect is a form of trauma.)
I love living in a wildly diverse food forest, and it will only become more diverse.
A NOTE ON SOCIETY
Nature shows the way, and these are some of the same reasons why a diverse society – if that society is actively inclusive – is a more healthy, vibrant, and resilient society. (Of course, if significant segments of society are actively working against diversity and inclusivity, it’s less healthy.)

The Benefits of Ecological Diversity
Diversity in regenerative projects like Milagros can take several forms, including plant diversity, wildlife diversity, and the diversity of ecosystems. Each type plays a crucial role in enhancing the health, productivity, and resilience of the land. By fostering and maintaining a rich variety of life forms and environments, you not only support the long-term sustainability of the ecosystem but also unlock a range of economic and ecological benefits. Here’s an in-depth look at these types of diversity and the multiple advantages they bring.
1. Plant Diversity
Plant diversity is the foundation of any healthy ecosystem. At Milagros, a wide range of plants—including native species, pioneer trees, food-producing plants, and ground cover—can create a robust and dynamic environment.
Benefits:
- Soil Health: Different plants have varying root structures that help aerate the soil, prevent erosion, and promote nutrient cycling. Nitrogen-fixing plants, for instance, enrich the soil, allowing other species to thrive.
- Resilience to Pests: A variety of plants creates a more complex environment for pests, reducing the likelihood of any one pest becoming a major problem. Companion planting can further enhance pest control by repelling harmful insects or attracting beneficial ones.
- Water Efficiency: Diverse plants make better use of available water by tapping into different layers of the soil. Deep-rooted trees can access groundwater, while shallow-rooted plants capture surface moisture.
2. Wildlife Diversity
The presence of diverse wildlife is a key indicator of a thriving ecosystem. Wildlife—ranging from insects and birds to mammals and reptiles—contributes to essential ecosystem functions like pollination, seed dispersal, pest control, and nutrient cycling.
Benefits:
- Pollination and Seed Dispersal: Birds, bats, and insects play crucial roles in pollinating crops and dispersing seeds. A diverse wildlife population ensures that plants continue to reproduce and thrive, which is especially important in food forests and agroforestry systems.
- Natural Pest Control: Predators such as birds, bats, and reptiles help control pest populations, reducing the need for chemical interventions. This is both ecologically sound and economically beneficial.
- Soil Fertility: Decomposers like insects and microorganisms break down organic matter, enriching the soil and improving its fertility. This supports plant growth and boosts crop yields.
3. Ecosystem Diversity
Diverse ecosystems—such as forests, grasslands, wetlands, and riparian zones—provide multiple habitats and support various species. At Milagros, ecosystems range from ponds and riparian areas to forests and grasslands, each contributing to the overall health and balance of the landscape.
Benefits:
- Resilience to Climate Variability: Diverse ecosystems can better withstand environmental stresses, such as droughts or floods. For example, riparian zones help with water retention and mitigate the impact of drought, while forests provide shelter and stabilize soil.
- Increased Productivity: Ecosystems with a variety of plants and animals are often more productive. This means they can support more biomass, produce more food, and store more carbon. This is particularly relevant for agroforestry systems, where food production and forest regeneration are integrated.
- Enhanced Biodiversity: Ecosystem diversity provides different niches for species to occupy, leading to higher biodiversity. This, in turn, stabilizes ecosystems by making them less vulnerable to shocks such as disease outbreaks or extreme weather.
Economic Benefits of Diversity
Diversity in plants, wildlife, and ecosystems doesn’t just bring ecological advantages—it also provides tangible economic benefits. For regenerative projects like Milagros, these benefits can be long-lasting and help create a sustainable model for both landowners and the surrounding community.
1. Productivity and Food Security
Diverse agroforestry systems that combine trees, shrubs, vines, and crops can produce a variety of food throughout the year, reducing dependence on any single crop. This diversification lowers the risks associated with crop failure and enhances food security for both personal consumption and market sale.
2. Ecotourism and Environmental Education
A rich diversity of plants, animals, and ecosystems can attract ecotourism, which provides an economic incentive to preserve and enhance biodiversity. Visitors interested in birdwatching, wildlife photography, or learning about agroforestry systems may visit the finca, providing an additional source of income. Likewise, the land can serve as a hub for educational workshops or community-based learning about sustainable agriculture and conservation.
3. Ecosystem Services
Healthy, diverse ecosystems provide valuable services such as water purification, carbon sequestration, and soil fertility. These services can reduce the need for costly inputs, such as fertilizers and irrigation, while increasing the overall productivity of the land. For instance, trees capture and store carbon, which can contribute to climate change mitigation and potentially lead to revenue through carbon credits.
4. Market Opportunities
Diverse plant systems allow for a wide range of products, from fruits and nuts to medicinal plants and timber. This diversification opens up different markets, including niche markets for organic and sustainably-produced goods. Additionally, the sale of native plants or seeds for regeneration projects elsewhere can provide an economic return while promoting biodiversity.
5. Risk Management
A diverse ecosystem is less vulnerable to the failure of any single component. In agricultural terms, this means that if one crop fails due to a pest outbreak or extreme weather, others will continue to produce, ensuring continued income. Diversifying the plant species also reduces the risk of soil depletion and erosion, preserving the land for future use.
Conclusion
The diversity of plants, wildlife, and ecosystems is essential for building a resilient, productive, and economically viable landscape. For a regeneration project like Milagros, fostering this diversity not only ensures the health of the ecosystem but also supports long-term sustainability by offering a wide range of ecological, social, and economic benefits. From increased food production and ecosystem services to new market opportunities and ecotourism, the benefits of diversity touch every aspect of life on the land. By embracing and nurturing this diversity, you can create a thriving, self-sustaining environment that benefits both people and nature.
The Edge Effct: Increased Diversity where Types of Ecosystems Meet
The edge effect is a phenomenon that occurs where two distinct ecosystems meet, creating a transition zone or “edge” between them. These edges often exhibit greater biodiversity and increased ecological activity compared to the core areas of the ecosystems they separate. This is because edge zones combine the resources, conditions, and species from both ecosystems, leading to an overlap of organisms and habitats. As a result, the edge becomes a hotspot for diversity, productivity, and ecological interaction.
Why Edges Increase Diversity
The increased diversity at the edge of two ecosystems occurs for several reasons:
- Resource Availability: The edge zone typically offers a wider variety of resources compared to either ecosystem alone. For example, sunlight, moisture levels, and soil nutrients may vary across the edge, supporting different types of plants and wildlife. Trees from the forest may provide shelter, while open grasslands offer more exposure to sunlight, creating a range of microclimates that can sustain a diverse group of species.
- Species Overlap: Species from both ecosystems converge at the edge, allowing organisms that thrive in both environments to coexist. In addition to species from each habitat, new species may evolve to specialize in the unique conditions of the edge zone, further boosting biodiversity.
- Habitat Variety: Edge zones often create a mix of habitats, such as shaded areas, open spaces, dense vegetation, and water bodies. This variety attracts species that require different living conditions for feeding, breeding, or shelter. Birds, for instance, may use the trees from one ecosystem for nesting and hunt for food in the open areas of the adjacent ecosystem.
- Increased Ecological Interactions: The edge brings together different species that might not otherwise interact, fostering new predator-prey dynamics, pollination relationships, and symbiotic partnerships. This can lead to a more complex and resilient ecological network.
Examples of Edge Zones
Edge zones can form naturally or be intentionally designed in regenerative landscapes like Finca Milagros. Common examples include:
- Forest-Grassland Edge: Where a forest meets a grassland, the edge benefits from the resources of both ecosystems. Trees offer shelter, while the open grasslands provide food and foraging opportunities. This edge zone can attract species like birds, insects, and mammals that take advantage of both environments.
- Water-Land Interface (Riparian Zones): The edge between aquatic ecosystems, such as rivers, ponds, or wetlands, and the surrounding land creates a rich habitat for species that rely on both water and terrestrial environments. This zone supports amphibians, water birds, and various plant species that thrive in moist conditions.
- Agroforestry Edges: In a food forest, the edges between cultivated land and natural forests or open spaces can boost biodiversity. The intentional mixing of crops, trees, and shrubs near the edge creates a productive and dynamic environment that supports both wild species and agriculture.
Benefits of the Edge Effect
The edge effect brings a host of ecological, agricultural, and economic benefits:
1. Enhanced Biodiversity
Edges support a wide range of species that can use resources from both ecosystems. This increased biodiversity contributes to the resilience of the landscape, making it more resistant to disturbances like drought, pests, or disease. The more species present, the more stable and adaptable the ecosystem becomes, as different species play roles in nutrient cycling, pest control, and pollination.
2. Improved Ecosystem Services
With increased biodiversity comes enhanced ecosystem services. For example, edges often host more pollinators, which can benefit both wild plants and crops. Similarly, natural pest control is improved as predators thrive in these diverse environments, reducing the need for chemical interventions.
3. Higher Productivity
Edge zones tend to be more productive because they combine the strengths of both ecosystems. In agriculture, this means that edge zones can yield more food or biomass than monoculture fields. For instance, a forest edge may support fruiting trees, ground cover crops, and wild plants, all of which contribute to overall productivity.
4. Habitat for Wildlife
Many species rely on edge habitats for breeding, feeding, and shelter. Birds, mammals, and insects are often drawn to edge zones where they can find abundant food and protection. This makes edge zones critical for wildlife conservation and biodiversity support.
Designing for the Edge Effect at Finca Milagros
In a regenerative project like Milagros, designing with the edge effect in mind can amplify biodiversity and productivity. Here are a few ways you might take advantage of this principle:
- Create Intentional Transitions: As you regenerate forests, plant food forests, and manage ponds or wetlands, consider how the edges between these ecosystems can be enhanced. Plant a mix of species that will thrive in the transition zone, such as shrubs, vines, and smaller trees that can make use of both the open areas and forest cover.
- Agroforestry Integration: By placing crops near the forest edge or planting diverse species along the edges of open areas, you can maximize the edge effect for both wildlife and productivity. Combining wild plants and cultivated crops ensures that you’re tapping into the biodiversity benefits that edges provide.
- Water-Related Edges: Riparian zones around your ponds and streams can be designed to increase the edge effect by encouraging a variety of plants and animals to thrive. Wetland species can mix with upland plants, creating a diverse habitat for amphibians, birds, and insects.
Conclusion
The edge effect plays a powerful role in increasing biodiversity and ecological productivity by combining the resources and species from adjacent ecosystems. In a project like Milagros, where you’re working to regenerate the land and create a thriving food forest, recognizing and enhancing the edges between different types of ecosystems can unlock significant ecological and economic benefits. By fostering these dynamic transition zones, you support a richer, more resilient, and more productive landscape that can sustain both human and natural communities.
Types of Ecosystems on Milagros
At Milagros, situated within a dry tropical forest, several types of ecosystems either naturally occur or can be cultivated as part of your regenerative project. In dry tropical forests, these ecosystems vary based on water availability, elevation, soil types, and human management. Here are some common ecosystems you might encounter or develop at Milagros:
1. Riparian Zones (Water-related Ecosystems)
These ecosystems occur along streams, rivers, or ponds, where water is more abundant. At Milagros, your large pond is an example of a riparian zone. These areas are crucial for biodiversity, providing habitat for aquatic species and species that depend on water, like birds and amphibians. These zones can also help with water filtration and prevent soil erosion.
2. Forest Ecosystems (Dry Tropical Forest Canopy and Understory)
Dry tropical forests are characterized by a mix of deciduous trees that shed their leaves during the dry season to conserve water. On Milagros, the established medium and large trees, along with the dense patches of pioneer trees, represent various stages of forest recovery. These forest areas support a range of wildlife, including insects, birds, and small mammals, while contributing to soil regeneration through organic matter decomposition.
3. Grasslands or Open Savannahs
Areas with more grass and fewer trees, like the grassy section you have at Milagros, are common in dry tropical forests. These open spaces can support grazing animals and are valuable for species that prefer open areas, such as certain birds and pollinators. These areas can also transition into more forested zones as part of your regeneration efforts by introducing more trees over time.
4. Agroforestry and Food Forest Systems
Agroforestry systems blend forested areas with food production, creating an ecosystem that mimics natural forests but is intentionally managed for human benefit. At Milagros, the leafy greens you are growing are part of this system. These systems can include a mix of fruit trees, medicinal plants, and other crops that thrive with minimal irrigation. Food forests combine both native and non-native species that thrive in the dry tropical climate.
5. Savanna-Woodland Transition Zones (Edge Ecosystems)
Where forest meets open grassland, these edge zones can exhibit a mix of species from both ecosystems. The edge effect increases biodiversity and productivity in these areas. You may have such transitional ecosystems at Milagros where forested areas meet more open land, creating vibrant zones with a mix of trees, shrubs, and grasses.
6. Regenerating Secondary Forests
As you work to regenerate areas of Milagros, some parts may resemble secondary forests—areas that are recovering from human intervention, grazing, or deforestation. These ecosystems are dynamic, often dominated by fast-growing pioneer species that stabilize the soil and improve conditions for other plants and animals to return.
7. Seasonally Dry Deciduous Forest
This is the dominant type of ecosystem in dry tropical forests, with trees that lose their leaves during the dry season to conserve water. These forests thrive in areas with distinct wet and dry seasons, and you likely have patches of this on Milagros, especially where medium-sized trees have grown back and contribute to the natural regeneration of the land.
By recognizing these ecosystems on Milagros, you can continue to guide your regeneration project with an understanding of how to foster biodiversity, restore the land, and maintain ecosystem services.
