Protective fence built for sea lions

The birth of a sea lion on a popular Dunedin dog-walking beach had Department of Conservation staff constructing a temporary fence to protect the mother and pup yesterday.

The hours-old pup was busy devouring milk from its 6-year-old mother, Gem, and seemingly oblivious to the activity.

Beach users contacted Doc staff after finding the pair on Tomahawk Beach.

Programme manager biodiversity assets David Agnew said it was rare for a sea lion to give birth near a popular beach.

"They usually choose more isolated spots." he said.

The 50 metres of bright orange fence would deter dogs and highlight the pair's position to beach users, while still allowing the mother to leave and get food, Mr Agnew said. He was assisted by biodiversity assets ranger Mel Young.

Warning signs would also be placed at the entrance to the beach, with dogs the main danger for the pair, he said.

In the past, a mother and pup had been moved from Smaills Beach, but ideally Gem and her pup would be left at Tomahawk, as staff did not want to put the animals under further stress.

Doc will reassess the suitability of the site daily and any volunteers interested in helping keep watch over the pair during the next week are invited to contact the department.

New Zealand sea lions are listed as a critically endangered species.

Last week, New Zealand Sea Lion Trust trustee Shaun McConkey filmed a dog attacking a young sea lion at Blackhead beach.

Even the least aggressive dogs can disturb marine animals breeding along Otago's coastline.

Under the Dog Control Act, it is an offence to harass wildlife and penalties include instant fines.

Protected or captive?

In general I am not keen on interfering with wildlife, and having watched "Mum" give birth to her last pup at Taieri Mouth, and watch DOC's efforts to "help" the pup by taking it away from the site and trying to feed it off another sea lion when Mum disappeared for too long, I know that sometimes even with best intentions we still get it wrong and can cause more harm than good.

The decision to fence off Gem and her pup from the public is laudable, but will cause them ongoing stress.  The new mum and her pup have keen volunteers watching their every move, families with kids, dogs and cameras coming down to see her daily, and nowhere to go even if they could because of the fence.  In this instance maybe a short sharp shock to their system to get them out of the public eye and into relative isolation at another location would be better than interminable scrutiny from the public, which must be causing them both ongoing stress.

At some stage Gem will need to go out and feed? What then? Will the bright orange fence stop her, will somebody be on hand to lower the fence for her when she wants to leave and return? And will she be reluctant to return to her bright orange enclosure. Also where will she hide her pup while she feeds - usually they would tuck them away into the sandhills - where at present she can't go.

Please think this through again DOC.  At the moment you don't have a protected animal you have a captive.  Be bold, move them then leave Gem alone to look after her pup in peace.
