Suitability to retain   LOW: Tree would require very large protection area

                        Hoop Pine is a Queensland native and a commercial timber that is
                        also endemic to the area of Cooroy. However large highly exposed
                        trees are less desirable close to new development sites.


                        While Araucaria species can tolerate areas of more frequent and
                        higher winds speeds; a fail safe for the species is to also be able to
                        shed limbs and reduce chance of the tree failing completely.


                        Cooroy has been subjected to freak storm events over the last 15
                        years and one such event in the last 3-4 years
                                                                       that caused major
                        damage to vegetation and throughout   the Cooroy community.

                        It is these local weather trends that would be of concern to the safety
                        of residential development around this tree.


                        There is also evidence of some minor limb failure, which is likely due
    Comments
                        to high wind speed events in the past. Remaining limbs have over
                        developed by extension; likely as a response to past limb loss.

                        Fruit drop is also considered a hazard. Cones of the Hoop Pine are
                        hard and heavy for their cricket ball size. During their cone
                        development cycle, generall risk management under Hoop Pines, is
                        to close off and restrict access to cone drop zones, or installing
                        permanent catch nets for safety.

                        Considered as an undesirable species to live with close to (within
                        target zone of) residential buildings and or high activity areas.

                        The life span of Hoop pines has been recorded to be over 400 years
                        and reach heights to 60m. Such trees require very large areas to
                        factor in space requirements to support continued growth
                        development and also the well being of neighbourinq residence.
                          Under the current design proposal it is not recommended that this
