Many manholes, drainage shafts, and ponds along roads, farms, and buildings act as deadly traps for small animals and amphibians. These creatures fall in and can’t climb out due to slippery, vertical walls—especially when wet. Despite previous efforts to fix this, millions still die every year. This not only harms local wildlife populations but also leads to costly blockages and cleanup for infrastructure operators.
The Invention
This invention introduces a smart, animal-friendly escape system that can either be built into new shafts or added to existing ones. The system includes a flexible “climbing aid” made of brushes, textured surfaces, and foldable parts that form a ramp-like escape channel. It guides animals toward light at the top and helps them climb out without slipping—even if the shaft is wet.
Key features
- Flexible brush ramps: Soft bristles adjust to openings and help animals grip as they climb.
- Expandable sections: The climbing path adjusts to different shaft depths.
- Anti-slip surfaces: Prevent backward slipping, even at steep angles.
- Weather-resistant mounting: Stays secure even during storms or flooding.
- Floatation options: Ensures escape from water-filled ponds or tanks.
What Makes It New
Unlike older attempts, this system is fully adjustable, uses the animals’ natural behavior (moving toward light), and is easy to retrofit. The modular design fits different environments and stays functional without blocking drainage or requiring electricity.
Benefits
- Saves countless small animals and amphibians from dying.
- Reduces environmental damage and species decline.
- Cuts maintenance costs for roads, farms, and utilities.
- Easy to install and adapt to many locations.
Wider Impact
This invention supports biodiversity, protects ecosystems, and offers a low-cost solution that benefits both wildlife and human infrastructure—turning deadly shafts into safe passageways for small creatures.
