Harold is a farmer who is heavily influenced by the traditional cropping and sheep rotation farming system. When he and his wife Helen started in Perenjori, Western Australia, this rotation system had to be adapted to suit the environmental restraints.  Now there are two Harold Park Dohne studs - one is located in Coorow and is managed by his son and daughter-in-law, Charles and Shayne, while the other is located in Mayanup and is run with the help of his daughter and son-in-law, Hayley and Clint.  Both of these farms are situated on different soil types and rainfall areas, so the rotation system has been adjusted yet again.

In 2004 Harold purchased his first Dohne rams. He was so impressed with the performance of the breed that he began the process of building up his flock to establish both a Commercial and Stud flock. From their inception both flocks have been bred using the following guiding principles, many of which have been developed during Harold's years in and around farming while some have come as a response to the social and environmental conditions of today: 

 

 

Resilience 
With the requirements of modern farming, it is important that the sheep are bred tough. There is no hand feeding except during droughts when animal welfare is at stake. 

Honesty 
Harold has a personal desire to show sheep as they will perform in the paddock not how they look if fed up. To back this belief up he offers a money back guarantee for stud ram purchases. 

True Dual Purpose 
A strong belief in the value of the wool industry maintains a focus on the true dual purpose with quality of wool and carcass weight given equal priority. 

Passion 
Harold is a dedicated sheep man who is very happy to spend time discussing or answering questions about the breed, specific rams or farming in general. 

Fairness 
The Helmsman auction system is used as he believes it is the fairest way to sell rams, allowing all an opportunity and the time to consider purchase options. 

Mules-Free 
With the industry heading towards mules-free Harold Park ceased mulesing in 2007. The Dohne breed are well suited to this with a low tendency to fly strike problems. So far the main benefit of this has been the lower labor input. 

Constant Improvement 
Constantly seeking to improve the quality of the genetics has resulted in targeted purchases of quality rams to bring into the stud flock.
