Environment rating

The environment rating or town rating (known as the Field Rank in  and island evaluation in ) is a gameplay element featured in all installments of the. The only way to check a town's status is by checking the wishing well, talking to Pelly or Phyllis at the civic center ( and ), or asking Isabelle at either the front desk in the Town Hall or at the Civic Consultation Counter at Resident Services.

After a number of conditions are met, the player may achieve "perfect town" status. This usually involves planting many trees and flowers (and in, public works projects) in addition getting rid of weeds and trash completely.

The benefits of achieving perfect town status include getting the gold watering can, lilies of the valley, rare mushrooms (in and ), and new public works project (in ).

In
In, the town's status is determined by the number of trees, weeds, flowers, and garbage in each acre of the town. There are 7 different ranks of quality determined by a simple hidden points system. Each acre has its own point value and these points are added to determine the town's overall rating. The rating can be determined by interacting with the wishing well. This rating affects the chance that a fish or insect will spawn in an acre, the rate that balloon presents spawn, and the chance that new villagers move in before reaching the limit of 15.

For fish and insects, the chance that a fish appears and the chance that an insect appears are calculated separately when the player enters an acre. Only one fish and one insect can be spawned from an acre at a time. At the lowest town rating, the chance for them to spawn is 50% and at rank 3 or higher, the chance is 100%. Below is a table that shows the points required for each rank, what the wishing well says at each rank, and the chance that a fish or a bug will spawn under that rank.

Each acre's points are calculated based on the number of trees within the acre. An acre must have between 9 and 17 trees to receive points. If any acre has an amount of trees outside of this range, the wishing well will tell the player that there are too many or too few trees in that acre. Below is a table that shows the points an acre is worth based on the amount of trees it contains and what the well may say.

Perfect town status
In addition to the points rankings, a "perfect town" status can also be reached. In order to reach this status, the town must be rank 6 and at least 17 out of the 30 acres in town must pass the following conditions.


 * The number of trees in each acre must be between 9 and 17 trees. This does not include the wishing well acre, train station acre, player house acre, lake acre, museum acre, or any beach acre.


 * There must not be any trash (Empty Can, Boot, or Old Tire) dropped anywhere outside or the town drops to rank 0 and the wishing well will say "I can abide this no more. There is no feeling worse than the prospect of being slowly buried in rubbish. You must clean up the trash in Acre !" Trash dropped at the dump does not count.


 * There must be less than 5 weeds or 4 fewer weeds than flowers in each acre. A flower offsets a weed, so an acre can contain 5 or more weeds only if there are enough flowers to offset them. If any acre contains too many weeds, the wishing well will say "When there are too many weeds... ...and areas in need of care and attention... ...a town feels very unsettled. Go to Acre  to see what is amiss."

Once a perfect town status has been reached, the wishing well will say "Everything is perfect!  is a very livable place." If the perfect town status is maintained for 15 days in a row, the well will say, "Your toil has made  a truly wonderful place. Your efforts shall be rewarded with a golden axe," and the spirit of the wishing well, Farley, appears and gives the player the unbreakable.

Japanese version differences
In and, the wishing well is instead a shrine. However, in, there is no appearance of Farley or the Golden Axe.

Unlike in and, in  and , garbage placed in the dump will affect Field Rank.

In, a perfect Field Rank also results in the Lily of the Valley flower growing around town.

Rare messages
The following messages are nearly impossible to get. This is because the wishing well always opts to tell the player where there are too few trees instead of rating the town and if there are enough trees in every acre. The town must be rank 4, 5, or 6 at that point. When receiving one of these messages, checking in the town status again defaults back to telling the player about where there are too few trees.

In and
In and, when talking with Pelly or Phyllis about the town's environmental status, the designated pelican will relay messages that other villagers have given her. Her response will inform the player if the town is prospering or not. Here are the responses that either Pelly or Phyllis will tell the player:


 * Horrible: "This place is the pits! Everything that can go wrong has gone wrong! There's not a single thing I like in this town!"


 * Bad: "I'm not sure what good it will do to write this, but... Could you try and be a bit more thoughtful about your town? Because at this rate..."


 * Neutral: "Hmm... it's not a passing grade, but it's not a failing grade either. It's like more than milk, but not quite a milk shake, you know what I mean?"


 * Good: "This town is fantastic! But even so, it still seems to be missing something"


 * Perfect: "Fantastic!  is in great shape right now! Yep, it's pretty sweeeeet!"

After Pelly or Phyllis relays the message, she will give a player a hint regarding how to make the town healthier. For example, at the "getting there" phase, Pelly may tell the player that some areas have inadequate green, which is a tip to plant more flowers and trees in areas lacking them. Phyllis's messages tend to be a little more straightforward about what the player needs to do.

Generally, for perfect environmental status in and, eight of the acres should be classed as 'perfect' and the rest as 'good' or better. This can be achieved by disposing weeds and trash, planting trees and flowers, and using watering cans to prevent dead flowers. Maintaining a perfect environmental status for 15 days will result in the player being rewarded the Golden Watering Can by Tortimer.

In
In, a points system is used instead, which is divided into three hidden categories. Public works projects are necessary for a positive rating, and the requirement for a specific number of trees/flowers in each acre no longer applies. Obtaining perfect town status can be achieved by building more public works projects (with the exception of building the trash bin and tire toy) and keeping the town clean of weeds and/or trash. The latter can be remedied with the Keep  Beautiful ordinance or by asking Leif to clean their town from weeds.

Advice to get a perfect town is given by various special characters in the game, relayed through Isabelle when speaking to her at the Town Hall. Each quote designates what the quality of the town is.

"Hmmmm... It's not a passing grade, but it's not really failing either... So middle ground! It's like this town is more than friends but not ready to be a couple yet. It needs real commitment!"

- Timmy and Tommy

"I think it's riding the so-so rails. So average!"

- Timmy and Tommy

"Well, they're certainly giving it their all! The difficult challenge is the reason town building is so worth it!"

- Digby

"Goodness gracious! Even from an academic standpoint, I must say this town is becoming quite good! If the town grows like this, I have no doubt that its value will keep soaring even higher, eh wot?"

- Blathers

"It seems that is starting to gain some attention as a popular sightseeing destination! I hope they continue to work hard to really keep revitalizing this town! Eek eek!"

- Porter

"It's great! The very best town ever! I wouldn't mind being mayor again for a town that looks like this!"

- Tortimer

"Why, it's amazing, and I truly mean that! This town is simply the best! They've clearly worked very hard! This old man is really pleased!"

- Phineas

"Great galloping grasshoppers! Were I to give this town a rating, I'd say that it's exemplary, old bean!"

- Nat

"Woohoo! What a glorious town! Pavé wants to just sprawl out right here and caress the ground... Viva !"

- Pavé

"Goodness gracious! I can say that, even from an academic standpoint, this town is simply the best! Hoo!"

- Blathers

In New Leaf, the Flower Clock and Town Hall renovation Public Works Projects become available after the town achieves perfect status. Maintaining a perfect town status for 15 days will result in Isabelle giving the player the Golden Watering Can.

In
In, the player's island is rated on a five-star system, based on two main factors: development points and scenery points. The island's rating can be viewed by speaking to Isabelle at Resident Services only after the 6th villager has moved in and unpacked. Isabelle will also relay a quote from another character about the island and suggest actions the player may take to improve their island rating (for example, placing more outdoor furniture and fences, planting or trimming foliage, moving in villagers, or building more stores). If the rating is five stars, Isabelle will congratulate the player for achieving a perfect score.

The environment rating plays a key role in Tom Nook's Project K, in which obtaining a 3-star rating is required for K.K. Slider to visit the island. The next day after getting a 3-star rating, K.K. Slider will visit and play "Welcome Horizons" in the plaza. Afterwards, he begins making his usual weekly visits. A 3-star rating is also required for the player to receive the Island Designer Construction Permit. Once the island reaches a 5-star rating, Isabelle sends the player the DIY recipe via the NookPhone.

Development
The island's development points are based on buildings, the number of villagers living on the island, and items placed outside.

If there are six or more of the same item in the same 8x8 area on the map, 0.5 development points are deducted for each duplicate. If there are eleven or more, 0.75 points are deducted for each duplicate.

Scenery
The island's nature points are based on the number of trees, bamboo trees, bushes, flowers, produce, and DIY furniture items on the island.

Vegetation/Plants
Various plants impact the player's town's environment. Sometimes, villagers will also comment about the town's environment when talking to the player.

Trees
The town's environment rating can decrease if there are not enough or too many trees in one or more acres. They can only contribute to a town's rating when fully grown. The same rules apply to bamboo and bushes, both of which first appeared in New Leaf.

In, each tree, bamboo, or bush adds one point to the island's nature score. However, having more than 220 nature points contributed through trees will render the player's island unable to reach perfect status, in which case Isabelle will notify the player that the island is overgrown.

Flowers
Flowers are one of the simpler ways to improve the town's environmental status (with the exception of, where they don't affect it). Placing at least one flower in each acre improves the town's environment immensely—a very high amount of them may cancel out other flaws in the environment, such as weeds. Any type of flower can be grown anywhere, but the player can keep it evenly distributed for a better environmental status. In all games before, players must water their flowers often, as wilted flowers impact the town status negatively.

In NH, a different amount of nature points are given towards the players score depending on the growth stage of the flower; stage 1 flowers (seeds) are worth 0.5 points, stage 2 and 3 flowers (stems and buds, respectively) are worth 0.7 nature points, and stage 4 flowers (fully grown) are worth 1 point each.

Weeds
A small number of weeds (two or three in most games) appear each day. The weeds will accumulate if they are not picked, so it is best for the town's status to pull weeds whenever they're seen. For a perfect town, no weeds should remain in a town overnight.

In, the island receives 30 development points if there are less than 100 weeds on the island; every 30 weeds after 100 removes 1 point. At 1000 weeds or more, the point bonus is zero.

Trash
Boots, cans, and tires fished out from the river or sea, as well as spoiled turnips, must never be placed on the ground, as they are considered trash and the environmental status of the town will immediately decrease. These items also attract the fly, an inexpensive bug. Trash should be placed in the dump, disposed for a fee at Re-Tail, thrown away in a trash bin furniture (which can be found in homes, built as a public works project, or placed outside), used in a DIY recipe, or sold.

Dropped items
Furniture, accessories, and other dropped items are considered trash. Therefore, items should not be left on the ground to reach perfect town status. Seashells, fruit, or other items naturally spawning on the ground (such as sticks or rocks) are not counted as dropped items.

Public works projects
In, a certain amount of public works projects are required to achieve perfect town status. Some projects, such as the Garbage Bin, detract from the town's score (but will not permanently keep it from attaining perfect status).

Bridges and Inclines
In New Leaf, bridges and inclines are considered Public Works Projects. However, in, they're counted separately within the development points of a player's island. There may be up to 8 bridges and 8 inclines on an island, with each project contributing 15 points once they are installed.

Furniture
As a new feature in, players are able to decorate their island with any type of furniture that is not wall-mounted (the only placeable wall-mounted furniture outside are door plaques, which have no impact on the island's rating). In accordance with this, furniture is no longer counted as trash as long as it is displayed rather than dropped. Villagers will also gift the player furniture items and recommend that they place them outside to improve the island's rating (although doing so with that specific item is not mandatory).

Either the island's nature score or development score will improve depending what kind and how much furniture is displayed. Every piece of non-DIY furniture is worth at least 1 development point, and an additional 0.5 point is added to items that are labeled as "outdoor furniture". DIY furniture contributes to the nature portion of the points system; any furniture that is at least 3 squares wide is worth 1 point, while anything smaller is only 0.25 points. There is also a penalty for having more than 6 of the same exact item (not counting customizations) within a 64-square block of the island.

Fences
In, the player may place fences around their island. Each fence piece is worth 0.2 points towards the island's development score.

Trivia

 * One of the quotes Isabelle restates from Wisp during the island evaluation is "It's a place I've been quietly watching. It's a secret to everybody. I don't want it to be famous." The "It's a secret to everybody" part is a reference to an identical quote commonly used in the The Legend of Zelda series.
 * Flick's description of the player's island when giving a 5-star evaluation is a truncated parody of the "this royal throne of kings" monologue from the 1595 play .
