Planting Trees

Right tree, right place, right purpose

Integrated Forestry Farm Systems

Integrated Forestry Farm Systems is a project demonstrating how integrating dairy and hill country sheep and beef farming with forestry for profitable, sustainable land use can assist landowners, iwi and rural professionals make well-informed forestry decisions and increase confidence in implementing forestry as a land-use option.

Perrin Ag Consultants Ltd in conjunction with PF Olsen completed ten case studies across the Bay of Plenty, Rangitikei and Waikato regions, evaluating a range of situations. Varying farm systems and landowner objectives enabled a variety of species and planting options to be investigated.

The Integrated Farm Forestry Systems project is a multi-agency funded research and extension project, led by Te Uru Rākau and co-funded by DairyNZ, the Waikato, Bay of Plenty and Horizons Regional Councils, Living Water (DOC-Fonterra partnership), Farmlands Co-operative and the Forest Growers Levy Trust.

Case Studies

The case studies provide outputs and resources to enable landowners who aspire to plant trees to have the knowledge and confidence to plant the right tree in the right place for the right purpose. Topics and information provided include:

  • Farm specific information on the Emission Trading Scheme (ETS), how carbon trading works, differences in carbon sequestration, ETS eligibility and the financial benefits and risks of registering plantings within the ETS.
  • Robust financial and environmental analysis demonstrating the potential returns, environmental impact and the performance of an integrated farm business.
  • Process for selecting wood harvesters and setting up wood harvesting agreements.
  • Best practice for tree management and harvest process for the case study farms, and how environmental impact at harvest can be mitigated through good planning and harvest management,
  • Illustrates a range of options for how natives can be established to provide integrated ‘best land-use’.
  • Illustrates the planning required and why site selections and silviculture regime are critical success factors for farm forestry.

Lee Matheson

Managing Director
Principal Consultant

B.Appl.Sc (Hons), FNZIPIM (Reg)

Lee came to agribusiness consultancy via the unlikely pathway of a suburban Wellington upbringing, an Honours degree in plant science and a six-year career in the financial markets. In his role as the firm’s MD, Lee doesn’t get out on-farm as much as he used to but makes the most of it when he does. While having swapped the paddock for the boardroom, Lee continues to provide advice in the areas of farm business strategy, farm system innovation, corporate governance, investment analysis and economic research.

Outside of Perrin Ag, Lee loves to spend his time coaching rugby, watching his three kids play sport and gardening with his wife Haidee.

“I love the challenge of empowering people in our primary sectors and the excitement of seeing clients achieving their aspirations. If we can encourage farmers to engage with their consumers, take a more active involvement in their supply chains and view their businesses through a wider lens, then I think our industries have a great future.”

Joel Hensman

Senior Consultant

BApplSc(Ag), MNZIPIM

Joel’s interest in agriculture began with his upbringing on a 1,000-hectare block of Kereru Station backing onto the Ruahine Ranges. Joel went on to earn a Bachelor of Ag Science at Massey University, laying the foundation for a career in the primary sector. On the back of a farming career and with over 12 years of professional experience, Joel joined Perrin Ag in 2024.

Outside of the workplace, Joel is a family man at heart and enjoys activities like mountain biking, tramping, and hunting. Living in a modest ‘tiny house’ and running a small farm operation, Joel is passionate about growing great food and helping people understand where their food comes from – all while keeping his boots dirty. “I help our clients step out of their daily realm and look at things through a broader lens. I am acutely aware of the mental health challenges facing our industry and the need to maintain the sustainability of our land and our people. We want farm practices that ensure long-term success without compromising farmers’ well-being.”

Mike brings a wealth of agri-tech and dairy systems expertise to Perrin Ag. After graduating with a Bachelor of AgriCommerce from Massey, he started his career with DairyNZ as a consulting officer where he ran discussion groups and managed farm supervision.

There are always new and better ways of doing things and we need to be at the forefront of that for our clients.”

Abbey Dowd

Consultant

B.Ag.Sc (Hons), MNZIPIM

Abbey joined Perrin Ag in February 2023 as part of the firm’s graduate recruitment programme, Empower.

Abbey grew up surrounded by dairy farms in a close-knit community in South Waikato. She saw first-hand how local farmers supported her community, which is what inspired her to study at Lincoln University.

Growing up in a rural community Abbey has always been impressed by how much local farmers contribute to the community. She wanted to help give back to the industry and play a part in helping our primary sector continue to produce quality food in a sustainable way.

In 2022, Abbey spent the summer as an intern on one of New Zealand’s first commercial deer milking operations. Her Honours project was researching deer milk alongside other more traditional milking operations and assessing the deer milking industry’s future production possibilities.

“Growing up I didn’t live on a farm, but I always knew I wanted to work in the farming sector. I wanted a role where there was a balance between working on and off farm and where I could support farmers to get the best out of their businesses.”

Sam Gray

Consultant

B.App.Sc(Hons), MNZIPIM, ASNM

Sam grew up on a dairy farm in the Far North. After graduating from the University of Otago in 2005 with an Honours degree in molecular biotechnology, he spent several years working in medical research in New Zealand and Scotland. Upon returning to New Zealand in 2012, he spent four seasons dairy farming in Northland before purchasing a 56 ha block in Taupо̄, where he was first exposed to farming under a nitrogen cap. Sam joined Perrin Ag in 2023 and brings his strong analytical skills that are grounded by a pragmatic approach to problem solving. Outside of farming and consultancy, you’ll likely find him fly fishing, hunting or snowboarding.

“A lot of farmers feel overwhelmed in the face of a rapidly changing regulatory landscape. I strive to help farmers understand what these environmental regulations mean for their business, and offer practical solutions that allow them to keep doing what they do best, whilst remaining compliant”.
