2: What Exactly is a Habitat? Defining the "Natural Home"
What is a habitat? Learn the fundamental definition of a 'natural home' and discover the essential requirements—from food supply to mineral resources—that dictate where plants and animals live.
While the word "habitat" is used frequently in nature conservation and ecology, it is often used without a clear definition. Many sources assume everyone already knows what it means, but to truly understand wildlife, we need to go back to basics.
The Dictionary Definition
At its core, a habitat is:
A natural home of an animal or plant.
The place in which a person, group, or class is normally found.
The word is closely linked to terms like habitation, inhabit, and habitable—all of which describe where something or someone lives.
What Makes a "Home" for Wildlife?
A "natural home" is more than just a location; it is a provider of essential resources. These resources differ slightly between animals and plants.
For Animals: Survival and Success
An animal’s preferred habitat is driven by two primary factors:
A reliable food supply: The food must be both plentiful and appropriate for that specific species.
Security: The area must provide shelter from the elements and a safe place to raise offspring.
For Plants: Resources and Competition
For plants, the requirements are focused on the environment's physical properties:
Essential Inputs: A plentiful supply of appropriate light, moisture, and minerals.
Space to Grow: The plant needs an environment with minimal competition for those specific resources.
The Naturalist's "Hidden" Insight
Every living thing has a preferred habitat or natural home. While this might seem obvious, it is a point frequently overlooked by casual observers. For the developing naturalist, acknowledging these specific needs is vital to understanding how nature works

The 5-Star Habitat Review
The 5-Star Habitat Review
In this activity, you will act as a "Property Surveyor" for wildlife. Choose a small area (a local park, a roadside verge, or your garden) and rate it based on the criteria discussed in the article.
Step 1: The Animal "Survey" (Food & Shelter)
Look at your chosen area through the eyes of a small mammal or a bird.
Food Supply: Can you see seeds, berries, nectar-rich flowers, or evidence of insects?
Security/Shelter: Are there thick bushes, hollow logs, or dense grass where an animal could hide from a hawk or a cold wind?
Rating: Give the area 1–5 stars for "Animal Habitation."
Step 2: The Plant "Survey" (Resources & Space)
Now, look at the ground and the canopy.
Light & Moisture: Is the ground bone-dry or suitably damp? Is there a mix of sun and shade?
The Competition Factor: Is the ground dominated by just one aggressive species (like thick ivy or nettles), or is there "space to grow" for a variety of different plants?
Rating: Give the area 1–5 stars for "Plant Diversity Potential."
Step 3: Identify the "Missing Link"
Look at your scores. If an area scored high for plants but low for animals, ask yourself: Why? * Example: A manicured lawn has plenty of light and moisture (Good for plants), but offers zero shelter and very little food variety (Bad for animals).
Step 4: The "Habitability" Conclusion
Write a one-sentence summary of your patch:
"This patch is a 4-star habitat for insects because of the varied flowers, but a 1-star habitat for nesting birds because there is no thick cover for protection."
