My new observations will be of weeds which is my new focus. Hoping to learn how to identify them as there are so many.

My older observations are of the Alex McKenzie Memorial Arboretum, south of Otautau, Southland. Many of the trees were planted by the NZ Forest Service in the 1950s and '60s however not all of the ID markers have survived. Do you know your exotic conifers and hardwoods? If so, I could use your help!
