Replant or coppice: a cash decision, not a silvicultural one

Once the harvest is done, the question comes: replant — pull the stumps and start over, ideally with a better clone — or conduct the coppice, letting the stumps sprout for the next cycle? The technical instinct pulls toward replanting: new genetics, a uniform stand, higher productivity. And that’s exactly where many operations make the right call silviculturally and the wrong one in cash terms.

Replanting is Capex, coppicing is Opex

Before it’s a nursery choice, this is a financial one — and the two options have opposite financial natures. Replanting is Capex: soil preparation, seedlings, planting, filling failures, intensive tending in the early years. A heavy, concentrated outlay today for a gain far ahead. Conducting the coppice is Opex: a light operating cost — sprout thinning, some tending — that keeps the forest standing without the investment of reopening the area.

Treating the two as merely “which yields more timber” ignores what matters most: when the money leaves and when it comes back.

The “ugly” coppice that wins

Here’s the point that inverts intuition. An irregular coppice, with gaps, with lower productivity than a fresh planting, can be worth more than a replant with the best clone available. Not because it produces more — it produces less — but because it delivers a better financial result: it doesn’t require the replanting Capex, it keeps cash in hand, and it still generates revenue in the next cycle.

Replanting spends now for a distant, discounted gain. Coppicing preserves cash and delivers early. Run both scenarios through the cash flow and the “ugly” coppice wins more often than technical culture will admit.

The number is future cash flow

The rule, in the end, is simple: the number that decides is future cash flow. Not mean annual increment, not the clone’s genetic gain, not “the manual says replant after so many cuts.” Run both scenarios — replant and coppice — through the same cash model, with the real cost of each, and choose the one that delivers more value.

Genetic gain is an input to the calculation, not the verdict. A clone 15% more productive doesn’t justify replanting if the Capex it demands, at the moment it demands it, destroys more value than it creates. Silviculture informs; cash decides.

Why silviculture pulls the wrong way

Technical culture is trained to maximize the forest: best material, best uniformity, best productivity per hectare. Legitimate goals — but goals of the stand, not of the asset. Optimizing the forest’s biology isn’t the same as optimizing the cash of whoever invests in it.

It’s the same logic as the harvest plan: the best technical decision and the best financial decision coincide only by accident. Replanting “because it’s the right thing to do” lets the wrong ruler decide an outlay that can weigh for years.

The right ruler

Replant or coppice isn’t a productivity choice — it’s a capital-allocation decision. Replanting is Capex; coppicing is Opex; and the right question is never “which forest is better,” but “which decision delivers more cash, net of what it cost.” Sometimes the answer is the new clone. Often it’s the imperfect coppice no one would put in the photo — and that, in the cash flow, is the one that creates value.

KSFlorestal treats replanting, coppicing, harvest and debt as what they are: decisions of the same cash flow.
