A research project of The Lighthouse

​

The Biodiversity Comparison Plots are one of the first active initiatives of The Lighthouse, exploring how different soil-care practices influence plant health, soil biology, insects, and overall ecological resilience.

This small-scale research project uses three identical plots, each planted with the same indicator species. By observing how the plants respond under different conditions, we can “read” the soil and understand what it needs to regenerate.

PLOT 1: CONVENTIONAL TILLED SOIL

This plot represents a common gardening and farming approach. Existing vegetation is removed and the soil is turned before planting. Tillage creates a clean seedbed and reduces competition from weeds, but it also disturbs soil structure, fungi, earthworms, and other organisms living underground.

​

Questions we are exploring:
How well do the plants grow?
How many weeds return?
How much watering and maintenance are required?
What happens to the soil over time?

​

​

PLOT 2: HEAVY MULCH

In this plot, the soil is covered with a thick layer of organic material. The mulch protects the soil from sun, wind, and heavy rain while helping retain moisture and suppress weeds. As the mulch breaks down, it feeds soil life and returns organic matter to the ground.

​

Questions we are exploring:
Does mulch reduce watering needs?
Does it suppress weeds?
Does it improve plant growth?
How does the soil change beneath the mulch?

​

​

PLOT 3: LIVING ROOTS

In this plot, the existing plants were left in place and the soil was not disturbed. Small planting areas were created for the crops while most of the vegetation and root systems remained alive. This approach follows a key principle of regenerative agriculture: keep living roots in the soil whenever possible.

Living roots feed soil organisms, help hold soil together, and support underground ecosystems throughout the growing season.

​

Questions we are exploring:
Can crops grow successfully alongside existing vegetation?
How does the soil stay covered and protected?
What differences can we see in moisture, biodiversity, and plant health?

WHY THIS MATTERS

Healthy soil is one of our most important natural resources. It stores water, supports biodiversity, grows food, and helps regulate climate. Around the world, farmers, gardeners, and land stewards are exploring different ways to improve soil health while reducing the need for chemicals, fuel, and intensive cultivation.

This garden is not about proving one method is right or wrong. It is an invitation to observe, ask questions, and learn from the results.

These observations will help shape future educational programs, community workshops, and regenerative practices at The Lighthouse’s long-term location.

Follow the Project

We invite the public to follow along here on the website, Instagram and Linkedin as the plots evolve. Updates will include photos, videos, observations, and reflections on what the land teaches us.
