Mountain Passes    

 by  Trygve  Roberts 

Trygve  was born in Knysna in 1949. Most of his childhood life was spent growing up in the Eastern Cape where he attended Selborne College and later completed a PMD at the Graduate School of Business in Cape Town. After a 10 year stint in Johannesburg, the ocean called and he took up a position with McCarthy Motor Holdings, where he soon became the youngest director in the group at the age of 33. In 1993 he started his own motor vehicle dealership and his been doing that for the last 25 years.

His interest in mountain passes started as a child and lay dormant until only five years ago, when an idea blossomed into the huge project he manages today.

June 7th: Talk at Tygerberg Nature Reserve

Nikita Swartz

WIL student of 2016 from Cape Peninsula University Of Technology

Tygerberg Nature Reserve

 

Topic: Tree of Heaven

Ailanthus altissima is an invasive species that produces ailanthrone. Ailanthrone is a chemical which stunts the growth of all vegetation in the vicinity of the tree.

This tree has vigorous growth rates; an extensive root system this often causes damage to infrastructure such as pipelines, walls and pavements.

This tree originates from china, it was brought here as an ornamental tree and is planted in gardens and on pavements throughout South Africa. This tree is now spreading uncontrollably to the detriment of biodiversity and infrastructure.

The tree of heaven is commonly found in urban ecosystems with many well established trees frequenting in gardens and built up areas. The species however is not dependent on urban systems to survive; an uncontrolled spreading of these species can result in it establishing itself in natural ecosystems.

According to the Alien Invasive Species Regulations Under National Environmental Management the Tree of Heaven species is a category 1b invader meaning that is needs compulsory control as part of management. Therefore it is becoming a vital thing to inform the public.

Within the talk topics will be:

  • Identification of the tree of heaven
  • Competitive invader
  • Control methods
  • What can you do

 

Time and Place : 19h00 for 19:30 at Kristo Pienaar Environmental Education Centre , Tygerberg Nature Reserve

Talk on 3rd May 2016  Title : Invasive Wasps causing havoc in Cape Town

The speaker is Marco Meyer who studied environmental and water science at UWC.

He was an intern at Department of Environmental Affairs before he started at the invasive species unit in 2014.

 

Content of the talk:

Two invasive wasp species have made Cape Town their new home. The European paper wasp is extremely abundant in the northern suburbs and has been making life for residents uncomfortable.

The German wasp is less abundant, but far more aggressive.

In this talk we will explain who these wasps are and what the City of Cape Town has been doing to assist residents.
