I sympathise with the injured driver as well as the animal involved in the tragic accident on Sunday morning (Rare deer put down after 3-vehicle accident; June 18).

With "critically endangered" wildlife thriving in wooded pockets of Singapore, Singaporeans have been asked to collect information on their sightings and also call the National Parks Board or Agri-food and Veterinary Authority, if necessary.

In addition, I suggest that the authorities study where and how animals near the Eco-Link enter the Bukit Timah Expressway, and take necessary actions such as installing fences and cautionary signs for vehicles at those spots.

The areas around Mandai and Bukit Brown should also be included in such studies.
