Even small native gardens provide *significant environmental benefits* in relation to their size because they serve as an important connector of habitat. My native 10x10-foot patch supports monarchs and is host to 15 species of bees. Your balcony garden or smallest corner can make a significant impact in a larger environmental solution.

Ecological Impact of Small Native Gardens
Garden Size	Pollinator Support	Habitat Connectivity	Biodiversity Increase
Balcony/Patio (50 sq ft)	5-10 specialist species	Neighborhood corridor	30% local increase
Small Yard (500 sq ft)	20-30 specialist species	Multi-block network	60% local increase
Parkway Strip (100 sq ft)	10-15 specialist species	Street-level connection	40% local increase
Community Plot (300 sq ft)	25+ specialist species	District-wide impact	70% local increase

Unique insect species flourish in small native plantings that provide essential resources: for example, monarch butterflies only require a single milkweed plant to complete their life cycle, and my single goldenrod supports three specialist species of bees. Your gardens create critically valuable refuge areas for these at-risk pollinators.

Habitat Stepping Stones

Connect fragmented urban green spaces
Enable wildlife movement across neighborhoods
Provide rest stops for migrating pollinators
Expand territory for beneficial insects

Specialized Support Systems

Host plants for butterfly reproduction
Nectar sources for specialist bee species
Seed banks for native plant regeneration
Nesting materials for solitary bees

Biodiversity Catalysts

Increase local insect diversity 10x
Attract birds through insect prey abundance
Support soil microorganisms naturally
Boost plant genetic diversity through seeding

Collective small gardens contribute to neighborhood biodiversity networks. My native strip is connected to six nearby gardens, creating a half-mile pollinator corridor. You participate in ecological mosaics that restore urban ecosystems as a whole.

Keystone plants amplify interactions in a limited area. For example, a single native oak tree can support hundreds of caterpillar species. I can attest that my potted milkweed sustains many generations of monarchs. When selecting a plant species, you optimize the benefits to the local ecology by choosing those that have the greatest impact as keystone plants.

This season, kick off your impact garden by selecting 3-5 key native plants. Depending on interest, consider planting milkweed for the butterflies or goldenrod for the bees. Yes, container plantings matter, and they matter tremendously! Your small effort becomes part of a much larger impact in environmental restoration.
