Planning and Construction

After installation, we recorded and monitored the footage within the pathway for 24 hours to observe the animal utilization. In order to capture the agile movements of the animals and facilitate future research, we made an effort to save high-quality footage within the limited budget.

Following the experiments conducted within the enclosure, we installed the experimental equipment on the private road within the premises of the Keep Foundation. The road is surrounded by forests on both sides, and we have confirmed the presence of raccoon dogs and squirrels in the vicinity through traces such as food remnants.

Taking into account the previous considerations, we designed and installed the bridge, considering its future use on public roads. The construction company performed structural calculations similar to those for a regular suspension bridge and thoroughly examined the construction methods.

o minimize costs, we opted for a collaborative approach in constructing the bridge, as conducting a full-scale construction project would be expensive. Staff members of the Keep Foundation and volunteers kindly offered their assistance in assembling the bridge. Finally, we used a crane to lift and install it. As depicted in the photographs, the bridge spans approximately 10 meters in length and stands 7 meters above the road. This height was necessary to accommodate specialized vehicles used for mowing the grass. While it may appear dangerously high for humans, it provides a safe vantage point for raccoon dogs and squirrels as they traverse the pathway.

We erected an additional utility pole beside the bridge and installed a video camera to monitor the usage of animals. We were able to observe various animals such as squirrels, raccoon dogs, and wild birds utilizing the pathway.
